Further, the first container 1 is attached with a first information carrying portion 11 carrying first information regarding the first container 1 . The first information includes, but is not particularly limited to, various types of identification information such as the type of liquid Q stored in the first container 1, for example. In this embodiment, the first information carrying part 11 is a one-dimensional code (barcode) and is attached to the side surface of the first container 1. Note that the first information carrying unit 11 is not limited to a one-dimensional code, but preferably includes at least one of a one-dimensional code and a two-dimensional code (QR code (registered trademark)), for example. . This code is stored in the control unit 101 of FIG. 1, and a label with a one-dimensional code and a two-dimensional code can be printed by a label printer connected to the control unit 101.

The second container 2 is attached with a second information carrier 12 that carries second information regarding the second container 2 . The second information includes, but is not particularly limited to, various types of identification information such as the type of liquid Q to be supplied into the second container 2, for example. In this embodiment, the second information carrying part 12 is a one-dimensional code, which is attached to the side surface of the second container 2. Note that the second information carrier 12 is not limited to a one-dimensional code, but preferably includes at least one of a one-dimensional code and a two-dimensional code, for example. This code is stored in the control unit 101 of FIG. 1, and a label with a one-dimensional code and a two-dimensional code can be printed by a label printer connected to the control unit 101.
Note that each of the first information carrying section 11 and the second information carrying section 12 may be configured using an RFID (radio frequency identifier) in addition to a one-dimensional code or a two-dimensional code. In this case, the code can be written to the IC chip by an RFID writer connected to the control unit 101.

As described above, the analysis system 10 includes the control section 101 and the information reading section 102.
When the liquid Q is supplied, that is, added and dispensed, the information reading section 102 reads first information from the first information carrying section 11 and reads second information from the second information carrying section before each supply. It is a device that reads information.

In this embodiment, the first information carrying section 11 and the second information carrying section 12 are each one-dimensional codes. Therefore, as shown in FIG. 2, the information reading section 102 includes a detection section 103 that optically detects a one-dimensional code, and a conversion section 104 that converts the detection result of the detection section 103 into an electrical signal. Consists of a code reader.

The detection unit 103 is a part that detects light reflected by a bar (black part) and a space (white part) of a one-dimensional code, that is, a barcode.
The conversion unit 104 is a unit that converts the detection result of the detection unit 103 into a binarized electrical signal that can be identified by the determination unit 105 of the control unit 101. Thereby, the determining unit 105 can accurately make a determination based on the detection result by the detecting unit 103.

As shown in FIG. 2, the information reading section 102 is electrically connected to the control section 101. The control unit 101 includes a determination unit 105 and a notification unit 106, and in this embodiment is configured with a personal computer as an example.
The determining unit 105 is a unit that compares the first information and the second information to determine whether or not the liquid Q can be supplied, and is configured with a CPU (Central Processing Unit). ing. Note that a program for determining supply quality is stored in advance in a storage unit (not shown) of the control unit 101.

The notification unit 106 is a part that notifies the results of the supply quality determination. This notification section 106 includes a light emitting section 107 that emits light and a sound generating section 108 that emits sound. By combining light emission and sound, it is possible to notify the result of the supply quality determination. Thereby, a worker who performs analysis work using the analysis system 10 can accurately understand the result of the supply quality determination. As will be described later, erroneous addition and erroneous dispensing can be prevented, and therefore the liquid Q can be added and dispensed accurately.

Note that in this embodiment, the light emitting unit 107 is a liquid crystal monitor built into the personal computer, and the audio generating unit 108 is a speaker built into the personal computer.
Further, the notification section 106 is not limited to having both the light emitting section 107 and the sound generating section 108, but may have at least one of the light emitting section 107 and the sound generating section 108 that emits sound. .
Further, as shown in FIG. 10, the analysis system 10 includes an analysis device 109 in addition to the control section 101 and the information reading section 102. The analysis device 109 may be, for example, a chromatography device, although it depends on the type of analysis.

Further, the analysis method of the present invention is a method of supplying liquid Q from the first container 1 to the second container 2 and performing an analysis using the liquid Q, and the analysis system 10 is used to carry out the analysis. It will be done.
As shown in Figure 3, this analysis method consists of an information reading step for reading information, a judgment step for making a judgment based on the reading result in the information reading step, and a notification step for notifying the result of the judgment in the judgment step. , has. The information reading step is executed by the information reading section 102, the judgment step is executed by the judgment section 105, and the notification step is executed by the notification section 106. When adding the liquid Q or dispensing the liquid Q, an information reading step, a judgment step, and a notification step are performed in order each time prior to the addition or dispensing.

Next, an example of how to use the analysis system 10 will be described with reference to FIGS. 4 to 10.
[1] First addition step As shown in FIG. 5, in the first addition step, a chemical solution container 3, a sample container 4A, a sample container 4B, and a sample container 4C are prepared.
The chemical solution container 3 stores the chemical solution Q1 in advance. Further, a barcode 31 printed by a label printer connected to the control unit 101 is attached to the drug solution container 3 .

The sample container 4A, the sample container 4B, and the sample container 4C each contain in advance a reaction liquid that reacts with the chemical solution Q1, that is, a sample liquid Q2 to be analyzed. Further, a barcode 41A is attached to the sample container 4A, a barcode 41B is attached to the sample container 4B, and a barcode 41C is attached to the sample container 4C. These barcodes are printed by a label printer connected to the control unit 101. The sample containers 4A, 4B, and 4C are collectively held in a rack 110.

In the first addition step, the chemical solution Q1 in the chemical solution container 3 is added to the sample container 4A and the sample container 4B, respectively, and the chemical solution Q1 is not added to the sample container 4C. In this case, the chemical liquid container 3 becomes the first container 1 as the supply source, and the sample container 4A and the sample container 4B each become the second container 2 as the supply destination. Therefore, the barcode 31 of the drug solution container 3 becomes the first information carrier 11 of the first container 1, and the barcode 41A of the sample container 4A and the barcode 41B of the sample container 4B serve as the second information carrier of the second container 2. This will be part 12.
Further, the amount of the chemical solution Q1 added to the sample container 4A is different from the amount of the chemical solution Q1 added to the sample container 4B. In this embodiment, the amount of the chemical solution Q1 added to the sample container 4A is greater than the amount of the chemical solution Q1 added to the sample container 4B. Note that the chemical solution Q1 is mixed with the sample solution Q2 to form a mixed solution Q3.

Further, in the first addition step, an addition procedure manual 91 indicating the procedure for adding the chemical solution Q1 is prepared in advance as electronic data, and can be selected and viewed by the control unit 101 in FIG. The addition procedure manual 91 includes an addition reagent (additional chemical liquid) code 911, an addition destination sample code, and a flag (hereinafter sometimes referred to as "reagent addition flag") 912 indicating whether or not to add the reagent (liquid Q), and The amount of added reagents, etc. are saved (attached). Since the sample to be added is different for each operation, the sample code and reagent addition flag 912 are either imported from another sample management system into the addition procedure manual 91 of the control unit 101 before performing the analysis operation, or are set in advance. Input by the worker.

Note that the added reagent code 911 corresponds to the barcode 31. That is, the added reagent code 911 is associated with the first information and is a chemical liquid information carrying section that carries chemical liquid information regarding the chemical liquid Q1.
Further, "SCode01" of the sample code and reagent addition flag 912 corresponds to the barcode 41A, "SCode02" corresponds to the barcode 41B, and "SCode03" corresponds to the barcode 41C. That is, the sample code and reagent addition flag 912 are associated with the second information, and are a reaction liquid carrier that carries reaction liquid information regarding the reaction liquid (sample liquid Q2).

Under such conditions, when an operator who performs analysis work using the analysis system 10 actually performs the first addition step, he or she first uses the information reading section 102 to read the bar in the chemical solution container 3. Before reading the first information from the code 31, the second information from the barcode 41A on the sample container 4A, and the second information from the barcode 41B on the sample container 4B, the operator The addition procedure manual 91 corresponding to the first addition step is selected on the section 101 (see step S101). Thereby, the control unit 101 recognizes that the first addition step of adding the chemical solution Q1 in the chemical solution container 3 to the sample container 4A and the sample container 4B is about to start. Note that this reading work is included in the information reading process.

Next, the operator uses the information reading section 102 to read the first information from the barcode 31 (first information carrying section 11) on the drug solution container 3 (see step S102). At this time, the determination unit 105 of the control unit 101 compares the first information from the barcode 31 and the addition reagent code 911 of the addition procedure manual 91 that has already been read (see step S103), and determines that the chemical solution Q1 is A judgment is made as to whether the chemical liquid should be used for addition in the first addition step. This determination of the quality of the chemical solution is included in the determination process. If the first information on both sides is the same, the chemical liquid quality judgment is good, that is, the chemical liquid Q1 is the chemical liquid that should be used for addition in the first addition step, and the notification unit 106 notifies the user to that effect. be done. This notification is included in the notification process. Further, by this notification, the operator can understand that the chemical solution container 3 is an appropriate container to be used in the first addition step.
After confirming that the chemical liquid container is appropriate, the operator uses the pipette 201 to aspirate the chemical liquid Q1 to be added to the sample from the chemical liquid container 3. The amount of suction of the medical solution Q1 at this time is displayed on the control unit 101, for example. Thereby, the operator can aspirate an appropriate amount of the chemical solution Q1.

On the other hand, the first information on both sides may be different. In this case, the chemical solution quality determination is negative, that is, the chemical solution Q1 is not the chemical solution that should be used for addition in the first addition step, and the notification unit 106 notifies that fact (see step S104). This allows the operator to understand that an inappropriate container that should not be used in the first addition step has been loaded, and take measures such as replacing this container with a proper container, that is, drug solution container 3. can be administered.

Next, the operator uses the information reading section 102 to read the second information from the barcode 41A (second information carrying section 12) on the sample container 4A (see step S105). At this time, the control unit 101 compares the first information from the barcode 41A with the sample code of the addition procedure manual 91 that has already been read and the reagent addition flag 912 (SCode01) (see step S106). Then, it is determined whether the supply destination in the first addition step is the sample container 4A. Also, confirm that the reagent addition flag is set to "Yes" (see step S106). That is, a judgment is made as to whether the supply is good or not. In addition, if there is no match in the code comparison, or if the reagent addition flag confirmation is "No", it is determined as "No", and the notification unit 106 notifies that the result of the supply quality judgment is "No" ( (See step S107).

If the result of the supply quality determination is good, the operator adds the aspirated chemical solution Q1 from the chemical solution container 3 to the pipette 201 into the sample container 4A. On the other hand, if the result of the supply quality determination is negative, an error notification is given to the operator (see step S107), and the operator stops adding the chemical solution Q1.
Note that after adding the chemical solution Q1 to the sample container 4A, the control unit 101 sets a flag indicating that the completion of the addition has been recognized in association with the sample code and the reagent addition flag 912 in the addition procedure manual 91. Thereby, by checking this flag when performing the next addition, it is possible to prevent excessive addition of the chemical solution Q1 to the sample container 4A for which addition has been completed.

Next, the operator uses the pipette 201 to aspirate the chemical solution Q1 to be added from the chemical solution container 3 to the next sample container 4B. Suppose that the operator mistakenly uses the information reading section 102 to read the second information from the barcode 41C (second information carrying section 12) on the sample container 4C instead of the sample container 4B (see step S105). ). The second information from the barcode 41C is compared with the sample code and reagent addition flag 912 (SCode02) of the addition procedure manual 91 that has already been read (see step S106). Then, it is determined whether the supply destination is the sample container 4B. That is, a judgment is made as to whether the supply is good or not. Further, the notification unit 106 notifies the result of the supply quality determination.

In this case, since the operator has read the barcode 41C of the wrong sample container 4C which is not the target for addition, the result of the supply quality determination is negative and an error notification is given (see step S107). The operator thereby stops adding the chemical solution Q1 to the wrong container (sample container 4C).

Moreover, if the operator finds the correct sample container 4B to be added without making a mistake, the operator reads the barcode 41B (see step S105). The second information from the barcode 41C is compared with the sample code and reagent addition flag 912 (SCode02) of the addition procedure manual 91 that has already been read, and a judgment is made as to whether or not the supply destination is the sample container 4B. Also, confirm that the reagent addition flag is set to "Yes" (see step S106). The notification unit 106 notifies the result of the supply quality determination. In this case, since the barcode 41B of the correct sample container 4B is read, the notification unit 106 displays that the result is good, and the operator confirms this and aspirates from the chemical solution container 3 into the pipette 201. Add the finished chemical solution Q1 to the sample container 4B. This allows the operator to add the reagent to the correct sample container 4B.

In addition, the control unit 101 reads the barcodes of all sample containers (in this example, sample containers 4A and 4B), and when all are determined to be good in the pass/fail judgment, the control unit 101 reads the barcodes of all the sample containers and the procedure manual. It is determined that the second information comparison has been completed (see step S108), and the notification unit 106 displays that addition to all sample containers has been completed, and the process ends. This allows the user to clearly know when the work has been completed.

Next, the operator uses the information reading section 102 to read the second information from the barcode 41C (second information carrying section 12) on the sample container 4C (see step S105). At this time, the control unit 101 compares the second information from the barcode 41C with the sample code and reagent addition flag 912 (SCode03) of the addition procedure manual 91 that has already been read (see step S106). As described above, the sample container 4C is not a supply destination for the chemical solution Q1, so the result of the supply quality determination is negative, and this fact is notified (see step S107). Thereby, the operator can stop adding the chemical solution Q1 to the sample container 4C.
As described above, in the first addition step, erroneous addition of the chemical solution Q1 can be prevented, and therefore, the addition of the liquid Q can be performed accurately.

[2] First dispensing process As shown in FIG. 6, in the first dispensing process, sample containers 5A, sample containers 5B, and sample containers 5C are prepared. Sample container 5A, sample container 5B, and sample container 5C are each in an empty state. Further, a barcode 51A is attached to the sample container 5A, a barcode 51B is attached to the sample container 5B, and a barcode 51C is attached to the sample container 5C. These barcodes are printed by a label printer connected to the control unit 101. The sample containers 5A, 5B, and 5C are collectively held in a rack 111.

In the first dispensing step, the mixed liquid Q3 in the sample container 4A is dispensed into the sample container 5A, the mixed liquid Q3 in the sample container 4B is dispensed into the sample container 5B, and the sample liquid in the sample container 4C is dispensed. Let us dispense Q2 into the sample container 5C. In this case, the sample container 4A becomes the first container 1 of the supply source, and the sample container 5A becomes the second container 2 of the supply destination. Therefore, the barcode 41A of the sample container 4A becomes the first information carrier 11 of the first container 1, and the barcode 51A of the sample container 5A becomes the second information carrier 12 of the second container 2.

Similarly, the sample container 4B becomes the first container 1 of the supply source, and the sample container 5B becomes the second container 2 of the supply destination. Therefore, the barcode 41B of the sample container 4B becomes the first information carrier 11 of the first container 1, and the barcode 51B of the sample container 5B becomes the second information carrier 12 of the second container 2.

Further, the sample container 4C becomes the first container 1 as the supply source, and the sample container 5C becomes the second container 2 as the supply destination. Therefore, the barcode 41C of the sample container 4C becomes the first information carrier 11 of the first container 1, and the barcode 51C of the sample container 5C becomes the second information carrier 12 of the second container 2.
In addition, in this embodiment, the amount of the mixed liquid Q3 dispensed into the sample container 5A is the same as the amount of the mixed liquid Q3 dispensed into the sample container 5B. Moreover, these amounts are larger than the amount of sample liquid Q2 dispensed into the sample container 5C.

Further, in the first dispensing step, a dispensing procedure manual 92 indicating the procedure for dispensing the liquid mixture Q3 is prepared in advance as electronic data, and can be selected and viewed by the control unit 101 in FIG. In the dispensing procedure manual 92, the sample code to be dispensed, the dispensing amount 921, and the dispensing amount are stored (attached). Since the sample to be dispensed differs for each operation, the sample code and dispensing amount 921 must be imported from another sample management system into the dispensing procedure manual 92 of the control unit 101 before performing the analysis work. , is input in advance by the operator.
In addition, if the sample is not to be dispensed, enter zero in the dispensing amount.

Note that "SCode01" of the sample code and dispensing amount 921 corresponds to barcodes 41A and 51A, "SCode02" corresponds to barcodes 41B and 51B, and "SCode03" corresponds to barcodes 41C and 51C. Furthermore, since all samples are to be dispensed, the amount to be dispensed for each sample is specified. That is, the sample code and the dispensing amount 921 are associated with the first information and the second information, and are a dispensing liquid information carrying part that carries dispensing liquid information regarding the dispensing liquid (mixture Q3).

When the operator actually performs the first dispensing process under such conditions, first, using the information reading section 102, the first information from the barcode 41A on the sample container 4A and the sample The second information from the barcode 51A on the container 5A, the first information from the barcode 41B on the sample container 4B, the second information from the barcode 51B on the sample container 5B, and the barcode on the sample container 4C. Before reading the first information from the code 41C and the second information from the barcode 51C on the sample container 5C, the operator performs the dispensing procedure corresponding to the first dispensing process on the control unit 101. Select book 92. As a result, the control unit 101 dispenses the mixed liquid Q3 in the sample container 4A into the sample container 5A, the mixed liquid Q3 in the sample container 4B into the sample container 5B, and the sample liquid Q2 in the sample container 4C. It is recognized that the first dispensing step of dispensing the sample into the sample container 5C will now start. Note that this reading work is included in the information reading process.

Next, the operator uses the information reading unit 102 to read the first information from the barcode 41A on the supply source sample container 4A (see step S201). At this time, the determination unit 105 of the control unit 101 compares the first information from the barcode 41A with the first information of the sample container 4A, which is the supplier of the dispensing procedure manual 92 that has already been read (step S202 ) to determine the suitability of the supplier's sample container. Then, if both pieces of first information are the same, it is confirmed that the dispensed amount is not zero. This determination of the quality of the supply source sample container and the check of the amount to be dispensed are included in the determination process. If both the supplier sample container quality judgment and the dispensing amount check are good, the sample dispensing quality judgment is good, that is, an appropriate sample was dispensed, and the notification unit 106 notifies this fact. This notification is included in the notification process. Further, by this notification, the operator can understand that the sample container 4A is a proper supply source container to be used in the first dispensing step. After confirming that the supply source container is appropriate, the operator uses the pipette 202 to aspirate the mixed liquid Q3 from the sample container 4A. The suction amount of the mixed liquid Q3 at this time is displayed on the control unit 101, for example. Thereby, the operator can aspirate an appropriate amount of the mixed liquid Q3. On the other hand, if either the result of the supplier sample container quality determination or the dispensing amount check is negative, the notification unit 106 will notify that fact (see step S203). Thereby, the operator stops suctioning the mixed liquid Q3.

Next, the operator uses the information reading unit 102 to read the second information from the barcode 51A on the sample container 5A (see step S204). At this time, the determination unit 105 of the control unit 101 compares the second information from the barcode 51A with the second information of the sample container 5A to which the already read dispensing procedure manual 92 is supplied (step S205). ) to determine whether it is suitable as a sample container for the destination. This determination of the quality of the supply destination sample container is included in the determination process. If both pieces of second information are the same, the judgment of quality of the destination sample container is good, that is, the sample container is an appropriate sample container, and the notification unit 106 notifies this fact. This notification is included in the notification process. Further, by this notification, the operator can understand that the sample container 5A is an appropriate destination container to be used in the first dispensing step. After confirming that the destination container is appropriate, the operator uses the pipette 202 to discharge the already aspirated mixed liquid Q3 into the sample container 5A. This completes the dispensing into the sample container 5A. On the other hand, if the result of the determination of the quality of the supply destination sample container is negative, the notification unit 106 will notify that fact (see step S206). Thereby, the operator stops discharging the mixed liquid Q3.
Note that, after dispensing the liquid mixture Q3 into the sample container 5A, the control unit 101 is preferably configured to recognize the completion of the dispensing as in the first addition step. Thereby, it is possible to prevent excessive dispensing of the mixed liquid Q3 into the sample container 5A after dispensing.

Next, the operator uses the information reading unit 102 to read the first information from the barcode 41B on the supply source sample container 4B (see step S201). At this time, the determination unit 105 of the control unit 101 compares the first information from the barcode 41B with the first information of the sample container 4B, which is the supplier of the dispensing procedure manual 92 that has already been read (step S202 ) to determine the suitability of the supplier's sample container. Then, if both pieces of first information are the same, it is confirmed that the dispensed amount is not zero. This determination of the quality of the supply source sample container and confirmation of the amount to be dispensed are included in the determination process. If both the supplier sample container quality judgment and the dispensing amount confirmation are good, the sample dispensing quality judgment is good, that is, the appropriate sample was dispensed, and the notification unit 106 notifies that fact, and the mixed liquid Q3 is The suction amount is displayed on the control unit 101. The operator confirms that the source container is appropriate and the suction amount, and uses the pipette 202 to aspirate the mixed liquid Q3 from the sample container 4B. On the other hand, if either the result of the supplier sample container quality determination or the dispensing amount confirmation is negative, the notification unit 106 will notify that fact (see step S203). Thereby, the operator stops suctioning the mixed liquid Q3.

Next, the operator uses the information reading unit 102 to read the second information from the barcode 51B on the sample container 5B (see step S204). At this time, the determination unit 105 of the control unit 101 compares the second information from the barcode 51B with the second information of the sample container 5B to which the already read dispensing procedure manual 92 is supplied (step S205). ) to determine whether it is suitable as a sample container for the destination. This determination of the quality of the supply destination sample container is included in the determination process. If both pieces of second information are the same, the judgment of quality of the destination sample container is good, that is, the sample container is an appropriate sample container, and the notification unit 106 notifies this fact. This notification is included in the notification process. Further, by this notification, the operator can understand that the sample container 5B is an appropriate destination container to be used in the first dispensing step. After confirming that the destination container is appropriate, the operator uses the pipette 202 to discharge the already aspirated mixed liquid Q3 into the sample container 5B. This completes the dispensing. On the other hand, if the result of the determination of the quality of the supply destination sample container is negative, the notification unit 106 will notify that fact (see step S206). Thereby, the operator stops discharging the mixed liquid Q3.

Next, the operator uses the information reading unit 102 to read the first information from the barcode 41C on the supply source sample container 4C (see step S201). At this time, the determination unit 105 of the control unit 101 compares the first information from the barcode 41C with the first information of the sample container 4C, which is the supplier of the dispensing procedure manual 92 that has already been read (step S202 ) to determine the suitability of the supplier's sample container. If the first information on both sides is the same, the amount to be dispensed is checked to make sure it is not zero. This determination of the quality of the supply source sample container and confirmation of the amount to be dispensed are included in the determination process. If both the supplier sample container quality judgment and the dispensing amount confirmation are good, the sample dispensing quality judgment is good, that is, the appropriate sample was dispensed, and the notification unit 106 notifies that fact, and the sample liquid Q2 is The suction amount is displayed on the control unit 101. The operator confirms that the supply source container is appropriate and the suction amount, and uses another pipette 202 to aspirate the sample liquid Q2 from the sample container 4C. On the other hand, if either the result of the supplier sample container quality determination or the dispensing amount confirmation is negative, the notification unit 106 will notify that fact (see step S203). Thereby, the operator stops suctioning the sample liquid Q2.

Next, the operator uses the information reading unit 102 to read the second information from the barcode 51C on the sample container 5C (see step S204). At this time, the determination unit 105 of the control unit 101 compares the second information from the barcode 51C with the second information of the sample container 5C to which the already read dispensing procedure manual 92 is supplied (step S205). ) to determine whether it is suitable as a sample container for the destination. This determination of the quality of the supply destination sample container is included in the determination process. If both pieces of second information are the same, the judgment of quality of the destination sample container is good, that is, the sample container is an appropriate sample container, and the notification unit 106 notifies this fact. This notification is included in the notification process. Furthermore, this notification allows the operator to understand that the sample container 5C is the appropriate destination container to be used in the first dispensing process. After confirming that the supply destination container is appropriate, the operator uses the pipette 202 to discharge the already aspirated sample liquid Q2 into the sample container 5C. This completes the dispensing. On the other hand, if the result of the determination of the quality of the supply destination sample container is negative, the notification unit 106 will notify that fact (see step S206). Thereby, the operator stops discharging the sample liquid Q2.

The control unit 101 also compares the first information of the sample containers and dispensing procedure manuals 92 of all supply sources, and the comparison of the second information of the sample containers and dispensing procedure manuals 92 of all supply destinations. It is determined that the first dispensing step is completed (see step S207), a message indicating that all dispensing in the first dispensing step is completed is displayed, and the process is terminated. This allows the user to clearly know when the work has been completed.
As described above, in the first dispensing step, erroneous dispensing of the liquid mixture Q3 can be prevented, and therefore the liquid Q can be dispensed accurately.

[3] Second Addition Step As shown in FIG. 7, in the second addition step, a chemical solution container 6 is prepared. The chemical solution container 6 stores the chemical solution Q4 in advance. Further, a barcode 61 is attached to the chemical liquid container 6.

In the second addition step, the chemical solution Q4 in the chemical solution container 6 is added to the sample container 5A and the sample container 5B, respectively, and the chemical solution Q4 is not added to the sample container 5C. In this case, the chemical liquid container 6 becomes the first container 1 that is the supply source, and the sample container 5A and the sample container 5B each become the second container 2 that is the supply destination. Therefore, the barcode 61 of the drug solution container 6 becomes the first information carrier 11 of the first container 1, and the barcode 51A of the sample container 5A and the barcode 51B of the sample container 5B serve as the second information carrier of the second container 2. This will be part 12. Note that the amounts of each chemical solution Q4 added are the same. Further, the chemical solution Q4 and the mixed liquid Q3 are mixed to form a mixed liquid Q5.

Further, in the second addition step, an addition procedure manual 93 indicating the procedure for adding the chemical solution Q4 is prepared in advance as electronic data, and can be selected and viewed by the control unit 101 in FIG. The addition procedure manual 93 stores (is attached to) an addition reagent (additional chemical solution) code 931, a sample code to which the addition destination is added, a reagent addition flag 932, an amount of addition reagent, and the like. Since the sample to be added is different for each operation, the sample code and reagent addition flag 932 are either imported from another sample management system into the addition procedure manual 93 of the control unit 101 before performing the analysis operation, or are set in advance. Input by the worker.

Note that the added reagent code 931 corresponds to the barcode 61. That is, the added reagent code 931 is associated with the first information and is a chemical liquid information carrying part that carries chemical liquid information regarding the chemical liquid Q4.
Moreover, "SCode01A" of the sample code and reagent addition flag 932 corresponds to the barcode 51A, "SCode02A" corresponds to the barcode 51B, and "SCode03A" corresponds to the barcode 51C. That is, the sample code and reagent addition flag 932 is associated with the second information, and is a reaction liquid carrier that carries reaction liquid information regarding the reaction liquid (mixed liquid Q3).

When an operator actually performs the second addition step under such conditions, first, using the information reading section 102, the first information from the barcode 61 on the chemical solution container 6 and the sample container are read. Before reading the second information from the barcode 51A in the sample container 5A, the second information from the barcode 51B in the sample container 5B, and the second information from the barcode 51C in the sample container 5C, The person selects the addition procedure manual 93 corresponding to the second addition step on the control unit 101 (see step S101). Thereby, the control unit 101 recognizes that the second addition step of adding the chemical solution Q4 in the chemical solution container 6 to the sample container 5A and the sample container 5B is about to start. Note that this reading work is included in the information reading process.

Next, the operator uses the information reading unit 102 to read the first information from the barcode 61 on the drug solution container 6 (see step S102). At this time, the determination unit 105 of the control unit 101 uses the first information from the barcode 61 and
Comparing it with the addition reagent code 931 of the addition procedure manual 93 that has already been read (see step S103), the chemical solution quality judgment is made as to whether the chemical solution Q4 is a chemical solution that should be used for addition in the second addition step. conduct. This determination of the quality of the chemical solution is included in the determination process. If the first information on both sides is the same, the chemical liquid quality judgment is good, that is, the chemical liquid Q4 is the chemical liquid that should be used for addition in the second addition step, and the notification unit 106 notifies the user to that effect. be done. This notification is included in the notification process. Furthermore, this notification allows the operator to understand that the chemical solution container 6 is an appropriate container to be used in the second addition step.
After confirming that the chemical liquid container is appropriate, the operator uses the pipette 203 to aspirate the chemical liquid Q4 to be added to the sample from the chemical liquid container 6. The suction amount of the chemical solution Q4 at this time is displayed on the control unit 101, for example. Thereby, the operator can aspirate an appropriate amount of the chemical solution Q4.

On the other hand, the first information on both sides may be different. In this case, the chemical solution quality determination is negative, that is, the chemical solution Q4 is not the chemical solution that should be used for addition in the second addition step, and the notification unit 106 notifies that fact (see step S104). This allows the operator to understand that an inappropriate container that should not be used in the second addition process has been loaded, and take measures such as replacing this container with a proper container, that is, the drug solution container 6. can be administered.

Next, the operator uses the information reading unit 102 to read the second information from the barcode 51A on the sample container 5A (see step S105). At this time, the control unit 101 compares the first information from the barcode 51A with the sample code of the addition procedure manual 93 that has already been read and the reagent addition flag 932 (SCode01A) (see step S106). Then, it is determined whether the supply source in the second addition step is the chemical liquid container 6 and the supply destination is the sample container 5A. Also, confirm that the reagent addition flag is set to "Yes". That is, a judgment is made as to whether the supply is good or not. In addition, if there is no match in the code comparison, or if the reagent addition flag confirmation is "No", it is determined as "No", and the notification unit 106 notifies that the result of the supply quality judgment is "No" ( (See step S107).

If the result of the supply quality determination is good, the operator adds the medicinal solution Q4, which has been aspirated from the medicinal solution container 6 to the pipette 203, to the sample container 5A. On the other hand, if the result of the supply quality determination is negative, an error notification is given to the operator (see step S107), and the operator stops adding the chemical solution Q4.
After adding the chemical Q4 to the sample container 5A, the control unit 101 sets a flag indicating that the completion of the addition has been recognized in association with the sample code and the reagent addition flag 932 in the addition procedure manual 93. Thereby, by checking this flag when performing the next addition, it is possible to prevent excessive addition of the chemical solution Q4 to the sample container 5A to which addition has been completed.

Next, the operator uses the pipette 203 to aspirate the drug solution Q4 from the drug solution container 6 to be added to the next sample container 5B. Suppose that the operator mistakenly uses the information reading section 102 to read the second information from the barcode 51C (second information carrying section 12) on the sample container 5C instead of the sample container 5B (see step S105). ). The second information from the barcode 51C is compared with the sample code and reagent addition flag 932 (SCode02A) of the addition procedure manual 93 that has already been read (see step S106). Then, it is determined whether the supply destination is the sample container 5B, that is, a determination is made as to whether the supply is good or bad. Further, the notification unit 106 notifies the result of the supply quality determination.

In this case, since the operator has read the barcode 51C of the wrong sample container 5C which is not the target for addition, the result of the supply quality determination is negative and an error notification is given (see step S107). The operator thereby stops adding the chemical solution Q4 to the wrong container (sample container 5C).

Moreover, if the operator finds the correct sample container 5B to be added without making a mistake, the operator reads the barcode 51B (see step S105). The second information from the barcode 51C is compared with the sample code of the addition procedure manual 93 that has already been read and the reagent addition flag 932 (SCode02A), and a judgment is made as to whether or not the supply destination is the sample container 5B. . In this case, the barcode 51B of the correct sample container 5B is read, so the code comparison is good. (See step S106) Also, confirm that the reagent addition flag is set to "yes" (see step S106). The notification unit 106 notifies the result of the supply quality determination. In this case, since the code comparison is good and the addition flag confirmation is also good, the notification unit 106 displays that the result is good, and the operator confirms it and removes the chemical solution from the chemical container 6. The chemical solution Q4 that has been aspirated into the pipette 203 is added to the sample container 5B. This allows the operator to add the reagent to the correct sample container 5B.

In addition, the control unit 101 reads the barcodes of all sample containers (in this example, sample containers 5A and 5B), and when it is determined that all are good in the pass/fail judgment, all the destination containers and procedure manuals It is determined that the second information comparison has been completed (see step S108), and the notification unit 106 displays that addition to all sample containers has been completed, and the process ends. This allows the user to clearly know when the work has been completed.

Next, the operator uses the information reading unit 102 to read the second information from the barcode 51C on the sample container 5C (see step S105). At this time, the control unit 101 compares the second information from the barcode 51C with the sample code of the addition procedure manual 93 that has already been read and the reagent addition flag 932 (SCode03A) (see step S106). This code comparison is good. Further, the addition flag is checked, but since the sample container 5C is not the supply destination for the chemical solution Q4 as described above, it is set as "not done". As a result, the addition flag confirmation becomes negative (see step S106). Although the code comparison is good, the addition flag confirmation is negative, so the result of the supply quality determination is negative, and this is notified (see step S107). Thereby, the operator can stop adding the chemical solution Q4 to the sample container 5C.
As described above, in the second addition step, it is possible to prevent erroneous addition of the chemical solution Q4, and therefore, the addition of the liquid Q can be performed accurately.

[4] Second Dispensing Step As shown in FIG. 8, in the second dispensing step, a sample container 7A and a sample container 7B are prepared. Sample container 7A and sample container 7B are each in an empty state. Further, a barcode 71A is attached to the sample container 7A, and a barcode 71B is attached to the sample container 7B. These barcodes are printed by a label printer connected to the control unit 101.

In the second dispensing step, the mixed liquid Q5 in the sample container 5A is dispensed into the sample container 7A, and the mixed liquid Q5 in the sample container 5B is dispensed into the sample container 7B. In this case, the sample container 5A and the sample container 5B become the first container 1 of the supply source, and the sample container 7A and the sample container 7B respectively become the second container 2 of the supply destination. Therefore, the barcode 51A of the sample container 5A and the barcode 51B of the sample container 5B become the first information carrier 11 of the first container 1, and the barcode 71A of the sample container 7A and the barcode 71B of the sample container 7B becomes the second information carrying part 12 of the second container 2. Note that the amounts of the mixed liquid Q5 to be dispensed are the same.

Further, in the second dispensing step, a dispensing procedure manual 94 indicating the procedure for dispensing the liquid mixture Q5 is prepared in advance as electronic data, and can be selected and viewed by the control unit 101 in FIG. The sample code to be dispensed, the amount to be dispensed 941, and the amount to be dispensed are stored (attached) to the dispensing procedure manual 94. Since the sample to be dispensed differs for each operation, the sample code and dispensing amount 941 must be imported from another sample management system into the dispensing procedure manual 94 of the control unit 101 before performing the analysis operation. , is input in advance by the operator.
In addition, if the sample is not to be dispensed, enter zero in the dispensing amount.

Note that "SCode01A" of the sample code and dispensing amount 941 corresponds to barcodes 51A and 71A, "SCode02A" corresponds to barcodes 51B and 71B, and "SCode03A" corresponds to barcode 51C. Also, since the samples of "SCode01A" and "SCode02A" are dispensed, the amount to be dispensed is specified for each sample, but the sample of "SCode03A" is not dispensed, so the amount to be dispensed is specified. Zero is set. That is, the sample code and the dispensing amount 941 are associated with the first information and the second information, and are a dispensing liquid information carrying part that carries dispensing liquid information regarding the dispensing liquid (mixed liquid Q5).

When the operator actually performs the second dispensing process under such conditions, first, using the information reading section 102, the first information from the barcode 51A on the sample container 5A and the sample The first information from the barcode 51B on the container 5B, the first information from the barcode 51C on the sample container 5C, the second information from the barcode 71A on the sample container 7A, and the barcode on the sample container 7B. Before reading the second information from the code 71B, the operator selects the dispensing procedure manual 94 corresponding to the second dispensing process on the control unit 101. As a result, the control unit 101 starts a second dispensing process in which the liquid mixture Q5 in the sample container 5A is dispensed into the sample container 7A, and the liquid mixture Q5 in the sample container 5B is dispensed into the sample container 7B. It is recognized that Note that this reading work is included in the information reading process.

Next, the operator uses the information reading unit 102 to read the first information from the barcode 51A on the supply source sample container 5A (see step S201). At this time, the determination unit 105 of the control unit 101 compares the first information from the barcode 51A with the first information of the sample container 5A, which is the supplier of the dispensing procedure manual 94 that has already been read (step S202 ) to determine the suitability of the supplier's sample container. Then, if both pieces of first information are the same, it is confirmed that the dispensed amount is not zero. This determination of the quality of the supply source sample container and the check of the amount to be dispensed are included in the determination process. If both the supplier sample container quality judgment and the dispensing amount check are good, the sample dispensing quality judgment is good, that is, an appropriate sample was dispensed, and the notification unit 106 notifies this fact. This notification is included in the notification process. Moreover, this notification allows the operator to understand that the sample container 5A is a proper supply source container to be used in the second dispensing process. After confirming that the supply source container is appropriate, the operator uses the pipette 204 to aspirate the mixed liquid Q5 from the sample container 5A. The suction amount of the mixed liquid Q5 at this time is displayed on the control unit 101, for example. Thereby, the operator can aspirate an appropriate amount of the mixed liquid Q5. On the other hand, if either the result of the supplier sample container quality determination or the dispensing amount check is negative, the notification unit 106 will notify that fact (see step S203). Thereby, the operator stops suctioning the mixed liquid Q5.

Next, the operator uses the information reading unit 102 to read the second information from the barcode 71A on the sample container 7A (see step S204). At this time, the determination unit 105 of the control unit 101 compares the second information from the barcode 71A with the second information of the sample container 7A to which the already read dispensing procedure manual 94 is supplied (step S205). ) to determine whether it is suitable as a sample container for the destination. This determination of the quality of the supply destination sample container is included in the determination process. If both pieces of second information are the same, the judgment of quality of the destination sample container is good, that is, the sample container is an appropriate sample container, and the notification unit 106 notifies this fact. This notification is included in the notification process. Further, by this notification, the operator can understand that the sample container 7A is an appropriate destination container to be used in the second dispensing process. After confirming that the destination container is appropriate, the operator uses the pipette 204 to discharge the already aspirated mixed liquid Q5 into the sample container 7A. This completes the dispensing into the sample container 7A. On the other hand, if the result of the determination of the quality of the supply destination sample container is negative, the notification unit 106 will notify that fact (see step S206). Thereby, the operator stops discharging the mixed liquid Q5.
Note that, after dispensing the liquid mixture Q5 into the sample container 7A, the control unit 101 is preferably configured to recognize the completion of the dispensing as in the first addition step. Thereby, it is possible to prevent excessive dispensing of the liquid mixture Q5 into the sample container 7A after dispensing.

Next, the operator uses the information reading unit 102 to read the first information from the barcode 51B on the supply source sample container 5B (see step S201). At this time, the determination unit 105 of the control unit 101 compares the first information from the barcode 51B with the first information of the sample container 5B, which is the supplier of the already read dispensing procedure manual 94 (step S202 ) to determine the suitability of the supplier's sample container. Then, if both pieces of first information are the same, it is confirmed that the dispensed amount is not zero. This determination of the quality of the supply source sample container and confirmation of the amount to be dispensed are included in the determination process. If both the supplier sample container quality judgment and the dispensing amount confirmation are good, the sample dispensing quality judgment is good, that is, the appropriate sample was dispensed, and the notification unit 106 notifies that fact, and the mixed liquid Q5 is The suction amount is displayed on the control unit 101. The operator confirms that the supply source container is appropriate and the suction amount, and uses the pipette 204 to aspirate the mixed liquid Q5 from the sample container 5B. On the other hand, if either the result of the supplier sample container quality determination or the dispensing amount confirmation is negative, the notification unit 106 will notify that fact (see step S203). Thereby, the operator stops suctioning the mixed liquid Q5.

Next, the operator uses the information reading unit 102 to read the second information from the barcode 71B on the sample container 7B (see step S204). At this time, the determination unit 105 of the control unit 101 compares the second information from the barcode 71B with the second information of the sample container 7B to which the already read dispensing procedure manual 94 is supplied (step S205). ) to determine whether it is suitable as a sample container for the destination. This determination of the quality of the supply destination sample container is included in the determination process. If both pieces of second information are the same, the judgment of quality of the destination sample container is good, that is, the sample container is an appropriate sample container, and the notification unit 106 notifies this fact. This notification is included in the notification process. Moreover, this notification allows the operator to understand that the sample container 7B is the appropriate destination container to be used in the second dispensing process. After confirming that the destination container is appropriate, the operator uses the pipette 204 to discharge the already aspirated mixed liquid Q5 into the sample container 7B. This completes the dispensing. On the other hand, if the result of the determination of the quality of the supply destination sample container is negative, the notification unit 106 will notify that fact (see step S206). Thereby, the operator stops discharging the mixed liquid Q5.

Next, the operator uses the information reading unit 102 to read the first information from the barcode 51C on the supply source sample container 5C (see step S201). At this time, the determination unit 105 of the control unit 101 compares the first information from the barcode 51C with the first information of the sample container 5C, which is the supplier of the dispensing procedure manual 94 that has already been read (step S202). ) to determine the suitability of the supplier's sample container. Then, if the first information on both sides is the same, the amount to be dispensed is confirmed. This determination of the quality of the supply source sample container and confirmation of the amount to be dispensed are included in the determination process. If both the supplier sample container quality judgment and the dispensing amount confirmation are good, the sample dispensing quality judgment is good, that is, the appropriate sample was dispensed, and the result of the supplier sample container quality judgment or the dispensing amount confirmation is good. If either one is negative, the sample dispensing quality judgment is negative, that is, an inappropriate sample was dispensed (see step S202).
As already mentioned, the dispensing amount of "SCode03A" coded in barcode 51C is set to zero, so the dispensing amount confirmation will be failed, the sample dispensing quality judgment will be failed, and that fact will be displayed. The notification is made by the notification unit 106 (see step S203). Thereby, the operator stops suctioning the mixed liquid Q5.

The control unit 101 also compares the first information of the sample containers and dispensing procedure manuals 94 of all supply sources, and the comparison of the second information of sample containers and dispensing procedure manuals 94 of all supply destinations. It is determined that the second dispensing process has been completed (see step S207), and a message indicating that all dispensing in the second dispensing process has been completed is displayed, and the process ends. This allows the user to clearly know when the work has been completed.
As described above, in the second dispensing step, erroneous dispensing of the liquid mixture Q5 can be prevented, and therefore the liquid Q can be dispensed accurately.

[5] Third addition step In the third addition step, operations similar to the third addition step and the third addition step are performed. That is, as shown in FIG. 9, in the third addition step, the chemical solution container 8 is first prepared. The chemical solution container 8 stores the chemical solution Q6 in advance. Further, a barcode 81 printed by a label printer connected to the control unit 101 is attached to the drug solution container 8 .

In the third addition step, the chemical solution Q6 in the chemical solution container 8 is added to the sample container 7A and the sample container 7B, respectively. In this case, the chemical solution container 8 becomes the first container 1 as the supply source, and the sample container 7A and the sample container 7B each become the second container 2 as the supply destination. Therefore, the barcode 81 of the drug solution container 8 becomes the first information carrier 11 of the first container 1, and the barcode 71A of the sample container 7A and the barcode 71B of the sample container 7B serve as the second information carrier of the second container 2. This will be part 12.
Further, it is assumed that the amount of the chemical solution Q6 added to the sample container 7A is different from the amount of the chemical solution Q6 added to the sample container 7B. In this embodiment, the amount of the chemical solution Q6 added to the sample container 7A is greater than the amount of the chemical solution Q6 added to the sample container 7B. Note that the chemical solution Q6 is mixed with the mixed solution Q5 to form a mixed solution Q7.

Further, in the third addition step, an addition procedure manual 95 indicating the procedure for adding the chemical solution Q6 is prepared in advance as electronic data, and can be selected and viewed by the control unit 101 in FIG. The addition procedure manual 95 stores (is attached to) an addition reagent (additional chemical liquid) code 951, a sample code to which the addition destination is added, a reagent addition flag 952, an amount of addition reagent, and the like. Since the sample to be added is different for each operation, the sample code and reagent addition flag 952 are either imported from another sample management system into the addition procedure manual 95 of the control unit 101 before performing the analysis operation, or are set in advance. Input by the worker.

Note that the added reagent code 951 corresponds to the barcode 81. That is, the added reagent code 951 is associated with the first information and is a chemical liquid information carrying part that carries chemical liquid information regarding the chemical liquid Q6.
Moreover, "SCode01B" of the sample code and reagent addition flag 952 corresponds to the barcode 71A, and "SCode02B" corresponds to the barcode 71B. That is, the sample code and reagent addition flag 952 are associated with the second information, and are a reaction liquid carrier that carries reaction liquid information regarding the reaction liquid (mixed liquid Q5).

When an operator actually performs the third addition step under such conditions, first, using the information reading section 102, the first information from the barcode 81 on the chemical solution container 8 and the sample container are read. Before reading the second information from the barcode 71A on the sample container 7A and the second information from the barcode 71B on the sample container 7B, the operator responds to the third addition step on the control unit 101. Select the addition procedure manual 95 to be added (see step S101). Thereby, the control unit 101 recognizes that the third addition step of adding the chemical solution Q6 in the chemical solution container 8 to the sample container 7A and the sample container 7B is about to start. Note that this reading work is included in the information reading process.

Next, the operator uses the information reading unit 102 to read the first information from the barcode 81 on the chemical liquid container 8 (see step S102). At this time, the determination unit 105 of the control unit 101 compares the first information from the barcode 81 and the addition reagent code 951 of the addition procedure manual 95 that has already been read (see step S103), and determines that the chemical solution Q6 is The quality of the chemical liquid is determined to determine whether the chemical liquid should be added in the third addition step. This determination of the quality of the chemical solution is included in the determination process. If the first information on both sides is the same, the chemical liquid quality judgment is good, that is, the chemical liquid Q6 is the chemical liquid that should be used for addition in the third addition step, and the notification unit 106 notifies that fact. be done. This notification is included in the notification process. Further, by this notification, the operator can understand that the chemical solution container 8 is an appropriate container to be used in the third addition step.
After confirming that the chemical liquid container is appropriate, the operator uses the pipette 205 to aspirate the chemical liquid Q6 to be added to the sample from the chemical liquid container 8. The amount of suction of the chemical solution Q6 at this time is displayed on the control unit 101, for example. Thereby, the operator can aspirate an appropriate amount of the chemical solution Q6.

On the other hand, the first information on both sides may be different. In this case, the chemical solution quality determination is negative, that is, the chemical solution Q6 is not the chemical solution that should be used for addition in the third addition step, and the notification unit 106 notifies that fact (see step S104). As a result, the operator can understand that an inappropriate container that should not be used in the third addition step has been read, and can take measures such as replacing this container with a proper container, that is, the drug solution container 8. can be administered.

Next, the operator uses the information reading unit 102 to read the second information from the barcode 71A on the sample container 7A (see step S105). At this time, the control unit 101 compares the first information from the barcode 71A with the sample code of the addition procedure manual 95 that has already been read and the reagent addition flag 952 (SCode01B) (see step S106). Then, it is determined whether the supply destination in the third addition step is the sample container 7A. Also, confirm that the reagent addition flag is set to "Yes". That is, a judgment is made as to whether the supply is good or not. Although the state is different from that shown in FIG. 9, if there is no match in the code comparison, or if the reagent addition flag is "not" confirmed, it is determined as negative, and the notification unit 106 informs the result of the supply quality determination. "No" will be notified (see step S107).

If the result of the supply quality determination is good, the operator adds the aspirated chemical solution Q6 from the chemical solution container 8 to the pipette 205 into the sample container 7A. On the other hand, if the result of the supply quality determination is negative, an error notification is given to the operator (see step S107), and the operator stops adding the chemical solution Q6.
After adding the chemical solution Q6 to the sample container 7A, the control unit 101 sets a flag indicating that the completion of the addition has been recognized in association with the sample code and the reagent addition flag 952 in the addition procedure manual 95. Thereby, by checking this flag when performing the next addition, it is possible to prevent excessive addition of the chemical solution Q6 to the sample container 7A in which addition has been completed.

Next, the operator uses the information reading unit 102 to read the second information from the barcode 71B on the sample container 7B (see step S105). At this time, the control unit 101 compares the first information from the barcode 71B with the sample code of the addition procedure manual 95 that has already been read and the reagent addition flag 952 (SCode02B) (see step S106). Then, it is determined whether the supply destination in the third addition step is the sample container 7B, that is, a determination is made as to whether the supply is good or bad. Further, if the codes do not match in the code comparison, it is determined that the supply quality is "fail", and the notification unit 106 notifies that the result of the supply quality determination is "fail".

If the result of the supply quality judgment is good, the operator adds the drug solution Q6 that has been aspirated from the drug solution container 8 to the pipette 205 into the sample container 7B. On the other hand, if the result of the supply quality determination is negative, an error notification is given to the operator (see step S107), and the operator stops adding the chemical solution Q6.
After adding the chemical solution Q6 to the sample container 7B, the control unit 101 sets a flag indicating that completion of the addition has been recognized in association with the sample code and reagent addition flag 952 in the addition procedure manual 95. Thereby, by checking this flag when performing the next addition, it is possible to prevent excessive addition of the chemical solution Q6 to the sample container 7B in which addition has been completed.

In addition, the control unit 101 reads the barcodes of all sample containers (in this example, sample containers 7A and 7B), and when all are determined to be good in the pass/fail judgment, the control unit 101 reads the barcodes of all the sample containers and the procedure manual. It is determined that the second information comparison has been completed (see step S108), and the notification unit 106 displays that addition to all sample containers has been completed, and the process ends. This allows the user to clearly know when the work has been completed.
As described above, in the third addition step, erroneous addition of the chemical solution Q6 can be prevented, and therefore the liquid Q can be added accurately.

[6] Measurement process As shown in FIG. 10, in the measurement process, an analyzer 109 is prepared. The operator loads the sample container 7A and the sample container 7B containing the liquid mixture Q7 into the analyzer 109, respectively. Then, by operating the analyzer 109, the sample liquid Q2 in the mixed liquid Q7 can be measured and analyzed.

As described above, in the analysis system 10, when adding liquid Q or dispensing liquid Q, prior to the addition or dispensing, each time the analysis system 10 performs an information reading process, a judgment process, and a notification process (from S101 to S101). S108, S201 to 207) are executed. This prevents erroneous addition and dispensing and allows even a single operator to perform accurate addition and dispensing. Furthermore, the analysis system 10 can be configured with the control section 101 and the information reading section 102, and therefore the analysis system 10 has a simple device configuration.
