First, the operator inserts the gas inspection device 70 to be inspected into the gas inspection device accommodation portion 60 of the adapter 50 attached to the accommodation portion 5 with the gas inspection device 70 being operated. Then, as described above, the suction nozzle 73 on the gas inspection device 70 side is connected to the air supply tube 62 on the adapter 50 side, and the communication unit 79 on the gas inspection device 70 side and the communication unit 53 on the adapter 50 side. Is ready for infrared communication. Then, the control unit 2 of the system main body 1 determines that the state in which the infrared communication becomes possible is the completion of the accommodation of the gas inspection device 70.

Then, the control unit 2 displays an initial screen (see FIG. 6A) on the display 3 in a state where the gas inspection device 70 is housed in the housing unit 5, and a “bump test” button on the initial screen is displayed. When operated by the user, execution of the inspection processing method is started.
In the inspection processing method, as shown in FIG. 4, the consistency check processing (# S1) and the predetermined grouping processing (# S2) are sequentially executed to determine the gas inspection machine 70 to be inspected (# S3). Then, the inspection process (# S4) is performed on the determined gas inspection device 70. After the execution of the inspection process (# S4), a cleaning process (# S6) is executed. When a plurality of gas inspection machines 70 are housed in the four housing units 5, a plurality of the gas inspection machines are set as inspection targets, and the plurality of gas inspection machines 70 set as the inspection targets are Inspection processing (# S4) is sequentially performed in series. In the present embodiment, various processes constituting the inspection processing method are sequentially executed in series. However, the processing order may be changed, at least a part of a plurality of processes may be duplicated, or another process may be performed. The execution procedure may be appropriately changed within a possible range, for example, by interposing a process therebetween.
Hereinafter, the details of each processing constituting the inspection processing method will be sequentially described.

[Consistency check processing]
In the consistency check processing (# S1) shown in FIG. 4, before the inspection processing (# S4) is performed, the adapter identification information acquired by the adapter identification information acquisition means 2b and the gas acquired by the gas inspection machine identification information acquisition means 2c are obtained. Check the consistency with the inspection machine identification information.
That is, in the consistency check processing (# S1), the adapter identification information of each storage unit 5 stored in the storage unit 4 in advance when the adapter 50 is mounted is referred to, and the gas of the gas inspection device 70 stored in the storage unit 5 is referred to. In a mode for comparing whether or not the inspection device identification information matches the adapter identification information associated with the same storage unit 5, whether or not an adapter 50 that is compatible with the gas inspection device 70 to be inspected is used. Check if. If not, the inspection process (# S4) is stopped and the user is notified of the stop. Conversely, if it is, the process proceeds to the next grouping process (# S2). .
By executing such a consistency check process (# S1), for example, a later check process (# S4) is executed in a state where the gas inspection device 70 which is not compatible with the adapter 50 is set in the adapter 50. Is prevented. Therefore, it is possible to avoid a problem that the inspection gas leaks or an erroneous inspection result is obtained due to the incompatibility of the combination of the gas inspection device 70 and the adapter 50.

[Grouping processing]
In the grouping process (# S2) illustrated in FIG. 4, a plurality of gas inspection devices 70 housed in the four housing units 5 are set as inspection targets, and each of the plurality of gas inspection devices 70 set as the inspection targets is checked. Grouping is performed according to the inspection gas supplied to the gas inspection device 70. Further, in this grouping process (# S2), various information on the inspection gas can be used as an index for grouping. In the present embodiment, the composition and concentration of the inspection gas supplied to the gas inspection device 70 are determined. This is used as an index for grouping.

After such a grouping process (# S2) is performed, and after the subsequent inspection process (# S4) is performed, it is checked whether or not the next gas inspection device 70 to be inspected belongs to the same group (# S5). ). If the next gas inspection device 70 belonging to the same group exists, the inspection process (# S4) for the gas inspection device 70 is preferentially executed. After performing the cleaning process (# S6), it is checked whether there is a gas inspection device 70 to be inspected belonging to another group (# S7). The process proceeds to the inspection process (# S4).
Then, by executing the grouping process (# S2) and sequentially performing the inspection process (# S4) for each group, the change of the composition and concentration of the inspection gas accompanying the switching of the inspection target is simplified. Has been

As shown in FIG. 5, in this inspection processing, an operator confirmation processing (# S10), an initial confirmation processing (# S12), a blockage alarm confirmation processing (# S13), and a suction are performed on the gas inspection device 70 to be inspected. The flow rate confirmation processing (# S14) and the gas alarm confirmation processing (# S15) are sequentially executed. Before the gas alarm confirmation process is performed, specifically, the concentration stabilization process (# S11) is performed in parallel with the execution of the initial confirmation process (# S12) to the suction flow rate confirmation process (# S14).
Hereinafter, the details of various processes constituting the inspection process will be described.

(Worker confirmation processing)
In the worker confirmation process (# S10), a worker confirmation screen (see FIG. 6B) is displayed on the display 3. Inspection items to be visually confirmed by the operator are displayed on the operator confirmation screen, and the operator visually inspects the gas inspection device 70 according to the display, and when there is no problem. To operate the "Confirmation completed" button displayed on the screen. When the "confirmation complete" button is operated, the worker confirmation processing (# S10) is terminated, and the worker confirmation screen (see FIG. 6B) on the display 3 is changed to a bump test screen (FIG. 6C). ) And the execution of the next initial confirmation process (# S12) is started.

(Initial confirmation processing)
FIG. 7 shows the operating states of various auxiliary machines and the gas flow states in the initial confirmation process (# S12). In this initial confirmation process (# S12), auto-zero setting and battery remaining amount confirmation are performed.
In the auto-zero setting, the switching state of the three-way valve V1 is set so that the air supply joint 5a to which the gas introduction unit 72 of the gas inspection machine 70 is connected is opened to the opening O1. Then, the gas inspection device 70 sucks the atmosphere OA from the gas introduction unit 72 via the opening O1 and supplies the sucked air OA to the sensor unit 76. In this state, a zero setting instruction is transmitted to the control unit 78 of the gas inspection device 70, and the control unit 78 of the gas inspection device 70 that has received the instruction sets the output of the sensor unit 76 to zero. On the other hand, in the battery remaining amount confirmation, the battery remaining amount of the gas inspection device 70 is received from the control unit 78 of the gas inspection device 70.
Then, when the auto-zero setting and the battery remaining amount confirmation are completed, the fact that the above-mentioned zero setting has been performed and the battery remaining amount are displayed on a bump test screen (see FIG. 6 (c)) displayed on the display 3; This initial confirmation processing (# S12) ends.

(Blockage alarm confirmation processing)
FIG. 8 shows the operation states of various auxiliary machines and the gas flow states in the blockage alarm confirmation processing (# S13). In this blockage alarm confirmation process (# S13), the gas inspection device 70 checks whether there is an abnormality in the blockage alarm function that outputs a predetermined blockage alarm when the gas introduction unit 72 is closed.
That is, in the blockage alarm confirmation processing (# S13), the outflow of gas from the air supply joint 5a is shut off while the air supply joint 5a is connected to the gas introduction unit 72 of the gas inspection device 70. The switching state of the three-way valves V1, V3, V4, and V5 communicating with the air supply joint 5a is set. Then, the state of the gas introduction unit 72 of the gas inspection device 70 is in a pseudo closed state, and the presence or absence of the output of the blocking alarm by the blocking alarm function of the gas inspection device 70 at that time is determined by the control unit 78 on the gas inspection device 70 side. Confirm by communication.

Then, if a blockage alarm is output in accordance with the cutoff of gas outflow from the air supply joint 5a, it is determined that the blockage alarm function of the gas inspection device 70 is operating normally. On the other hand, when the blockage alarm is not output due to the cutoff of the gas outflow from the air supply joint 5a, it is determined that the blockage alarm function of the gas inspection device 70 is not operating normally. In addition, as for the gas inspection device 70 having such an abnormality in the blocking alarm function, the blocking abnormality in which the suction flow rate becomes substantially zero before the gas suction flow rate deviates from the appropriate flow rate range. It can be determined that there is also a possibility.
Then, the presence / absence of an abnormality of the blockage alarm function of the gas inspection device 70 is displayed on the bump test screen (see FIG. 6C) displayed on the display 3, and the blockage alarm confirmation processing (# S13) is ended. .

  Further, upon ending the blockage alarm confirmation process (# S13), the next suction flow rate confirmation process (# S14) is executed only for the gas inspection device 70 having no abnormality in the blockage alarm function. On the other hand, when it is determined that there is an abnormality in the blockage alarm function, it is abnormal as a comprehensive judgment in order to avoid unnecessary execution of the subsequent processing including the gas alarm confirmation processing (# S15) for the gas inspection device 70. A message to that effect is displayed (# S17), and the inspection process (# S4 in FIG. 4) is terminated to streamline the inspection process.

(Suction flow confirmation processing)
FIG. 9 shows the operating states of various auxiliary machines and the gas flow states in the suction flow rate confirmation processing (# S14). In this suction flow rate confirmation processing (# S14), it is checked whether there is any suction flow rate abnormality in which the gas suction flow rate from the gas introduction unit 72 of the gas inspection device 70 deviates from the appropriate flow rate range.
That is, in the suction flow rate confirmation process (# S14), the switching state of the three-way valve V1 and the three-way valve V3 is set and opened in a state where the air supply joint 5a is connected to the gas introduction unit 72 of the gas inspection device 70. The air supply joint 5a is opened to the atmosphere via an air opening path leading to the section O2. Then, the gas inspection device 70 sucks the atmosphere OA from the gas introduction unit 72 through the open-to-atmosphere path, so that the gas is measured by the flow meter Mf1 (an example of the open flow measurement unit) provided in the open-to-atmosphere path. The obtained gas flow rate is acquired as the gas suction amount of the gas inspection device 70, and it is determined whether or not the gas inspection device 70 has a suction flow rate abnormality for which an appropriate gas suction flow rate cannot be secured.
Then, after the presence or absence of the suction flow rate abnormality of the gas inspection device 70 is displayed on the bump test screen (see FIG. 6C) displayed on the display 3, the suction flow rate confirmation processing (# S14) is ended.

  Further, upon ending the suction flow rate abnormality confirmation processing (# S14), the following gas alarm confirmation processing (# S15) is executed only for the gas inspection device 70 having no suction flow rate abnormality. On the other hand, if it is determined that the suction flow rate has an abnormality, it is determined as an overall judgment that there is an abnormality in order to avoid unnecessary execution of the subsequent processing including the gas alarm confirmation processing (# S15) for the gas inspection device 70. After the display (# S17), the inspection process (# S4 in FIG. 4) is completed to streamline the inspection process.

(Concentration stabilization processing)
FIGS. 8 to 10 show the operation states of various auxiliary machines and the gas flow states in the concentration stabilization processing (# S11). In the concentration stabilization process (# S11), the inspection gas G1 having a stable flow rate and concentration is supplied to the gas introduction unit 72 of the gas inspection device 70 from the beginning of the later execution of the gas alarm confirmation process (# S15) to accurately perform the process. In order to obtain a proper inspection result, this is a process executed at the time of executing the blockage alarm confirmation process (# S13) or the suction flow rate confirmation process (# S14) before the execution of the alarm confirmation process (# S15). The check is performed in parallel with the execution of the initial confirmation process (# S12) to the suction flow rate confirmation process (# S14) (see FIGS. 8 and 9). Until the flow rate and the concentration of the use gas G1 are stabilized, the alarm check process (# S15) is executed in a standby state (see FIG. 10).

That is, in the concentration stabilization processing (# S11), the inspection gas G1 generated by the dilution processing by the above-described dilution processing means 6 is exhausted to the outside to stabilize the concentration of the inspection gas G1.
Specifically, by opening the two-way valve V7 and the flow regulating valve V10 and setting the switching state of the three-way valve V8, the raw material gas G0 taken out of the gas container C1 (in the present embodiment, stored in the gas container C1). The source gas G0 obtained is used, but another gas container C2 may be used.) After the pressure is stabilized by the pressure regulator R2, the gas is passed through the flow meter Mf2. And supplies it to the junction B1. At the same time, by operating the pump P1, opening the two-way valve V11 and setting the switching state of the three-way valves V12 and V13, the atmospheric OA taken from the opening O3 flows through the filter F3 and the flow meter Mf3. And supply it to the junction B1. Thus, at the junction B1, the source gas G0 passed through the source gas path 6b provided with the flow meter Mf2 is diluted by the atmospheric OA passed through the atmosphere supply path 6a provided with the flow meter Mf3. A so-called dilution process is performed to generate the inspection gas G1.

The flow rate of the source gas G0 supplied to the junction B1 is controlled by adjusting the opening degree of the flow control valve V10, while the flow rate of the atmospheric OA supplied to the junction B1 is controlled by adjusting the output of the pump P1. Have been. Then, by these controls, the flow rate and concentration of the inspection gas G1 are adjusted to desired flow rates and concentrations.
In such a dilution process, the set flow rate of the raw material gas G0 set according to the dilution ratio of the raw material gas G0 is set according to the dilution ratio so that the capacity of the gas containers C1 and C2 may be as small as possible. It is set to be smaller than the set flow rate of the atmospheric OA set.
In the concentration stabilization process (# S11), the switching state of the three-way valves V4 and V5 is set so that the inspection gas G1 generated at the junction B1 is opened via the three-way valves V4 and V5. It is supplied to O4 and is exhausted to the outside through the opening O4. That is, the supply destination of the inspection gas G1 is switched from the air supply joint 5a on the gas inspection machine 70 side to the external opening O4 so that the inspection gas G1 can be exhausted.

  In the concentration stabilization process (# S11), the two-way valves V2 and V6 are opened while operating the pump P2, so that the surrounding air taken in from the opening 59 of the adapter 50 is exhausted EA from the opening O4. It is in a state of discharging to the outside. That is, the inspection gas G1 exhausted to the outside through the opening O4 is diluted by the surrounding air taken in from the opening 59 of the adapter 50, and the inspection gas G1 is exhausted to the outside with a high concentration. That has been avoided.

  Further, at the start of the execution of the above-described dilution process, that is, at the start of the execution of the concentration stabilization process (# S11), the opening degree of the flow control valve V10 is temporarily increased, and the flow rate of the raw material gas G0 is reduced. The flow rate is set higher than the set flow rate according to the dilution ratio of the raw material gas G0. As a result, the concentration of the inspection gas G1 generated at the junction B1 rises quickly and reaches an appropriate concentration, and as a result, in a state of waiting for the start of the execution of the alarm confirmation process (# S15). The execution time of the density stabilization process (# S11) can be made as short as possible.

  Further, as shown in FIG. 9, during the execution of the concentration stabilization processing (# S11) in a state of waiting for the start of the execution of the alarm confirmation processing (# S15), the same as the above-described initial confirmation processing (# S12) Then, by opening the air supply joint 5a to which the gas introduction unit 72 of the gas inspection device 70 is connected to the opening O1, the gas inspection device 70 releases the air OA from the gas introduction unit 72 through the opening O1. Try to aspirate.

(Gas alarm confirmation processing (dilution processing))
FIG. 11 shows the operating states of the various auxiliary machines and the gas flow states in the gas alarm confirmation processing (# S15) when performing the dilution processing. In this gas alarm confirmation process (# S15), the inspection gas generated by the dilution process is supplied to the gas introduction unit 72 of the gas inspection device 70 via the branching unit B2 serving as the gas supply unit and the supply joint 5a. G1 is supplied to check whether the gas alarm function of the gas inspection device 70 is abnormal.
In this gas alarm confirmation process (# S15), the inspection gas G1 diluted with the atmospheric OA that has not been subjected to the drying process by the dilution process is supplied to the gas inspection device 70. The part 76 is maintained under the same condition as normal atmospheric OA containing moderate moisture without excessive drying, and operates under the same conditions as during normal use.

That is, in the gas alarm confirmation process (# S15) shown in FIG. 11, the switching state of the three-way valves V1, V4, and V5 is set from the state of the concentration stabilization process (# S11) in FIG. The inspection gas G1 supplied to the gas inspection device 70 is supplied to the gas introduction portion 72 of the gas inspection device 70 via the branch portion B2 as a gas supply portion and the air supply joint 5a. G1 is sucked. Then, the inspection gas G1 containing the specific component is introduced from the gas introduction unit 72 into the gas inspection device 70, and at that time, the gas alarm function of the gas inspection device 70 operates normally and outputs a gas alarm. Whether or not there is an abnormality in the gas alarm function of the gas inspection machine 70 is confirmed by communicating with the control unit 78 on the gas inspection machine 70 side.
Then, after the presence or absence of an abnormality of the gas alarm function of the gas inspection device 70 is displayed on the bump test screen (see FIG. 6C) displayed on the display 3, the alarm confirmation processing (# S15) is ended.

  Further, in the gas alarm confirmation process (# S15) shown in FIG. 11, the inspection gas G1 larger than the gas suction flow rate of the gas inspection device 70, that is, the suction flow rate of the suction pump 75 on the gas inspection device 70 side, is output to the gas inspection device. The gas is supplied to a branching section B2 which is a gas supply section communicating with a gas introduction section 72 of 70. Then, although the inspection gas G1 that has not been sucked is present in the gas introduction unit 72 of the gas inspection device 70, the inspection gas G1 is discharged to the outside from the opening O4 through the three-way valve V5. Accordingly, the gas inspection device 70 sucks the inspection gas G1 without shortage, and further maintains the suction flow rate at an appropriate suction flow rate regardless of the supply flow rate of the inspection gas G1 on the system body 1 side. Therefore, it operates under the same conditions as during normal use.

  In ending the gas alarm confirmation processing (# S15), the previous blockage alarm confirmation processing (# S13) and the suction flow rate confirmation processing (# S14) for the gas inspection device 70 having no gas alarm abnormality. Is also normal, a message indicating normality is displayed as a comprehensive judgment (# S16), and the inspection process (# S4 in FIG. 4) ends. On the other hand, when it is determined that there is a gas alarm abnormality, the fact that the gas alarm is abnormal is displayed as a comprehensive judgment (# S17), and the inspection processing (# S4 in FIG. 4) ends.

(Gas alarm confirmation processing (non-dilution processing))
In the gas alarm confirmation process (# S15) shown in FIG. 11 described above, the dilution process for diluting the raw material gas G0 taken out of the gas container C1 with the atmospheric OA to generate the inspection gas G1 is performed. Instead of this dilution process, a gas alarm confirmation process can be performed in the case of performing a non-dilute process in which the raw material gas G0 taken out of the gas container C1 is used as an inspection gas without being diluted as it is. Details will be explained.
In the gas alarm confirmation processing (# S15), since the raw material gas G0 is used as it is as the inspection gas, the above-described concentration stabilization processing (# S11) is omitted.

  FIG. 13 shows the operating states of the various auxiliary machines and the gas flow states in the gas alarm confirmation processing (# S15) when performing the non-dilution processing. In this gas alarm confirmation process (# S15), the gas is supplied as a check gas to the gas introduction unit 72 of the gas inspection device 70 by the non-dilution process through the branching unit B2 and the air supply joint 5a. The source gas G0 taken out of the container C1 is supplied to check whether or not the gas alarm function of the gas inspection device 70 is abnormal.

That is, in the gas alarm confirmation process (# S15) shown in FIG. 13, the operation of the pump P1 is stopped, the three-way valve V13 is closed, and the intake of the atmospheric OA from the opening O3 is stopped. At the same time, by opening the flow control valve V10 and setting the switching state of the three-way valve V8, the pressure of the raw material gas G0 taken out of the gas container C1 is stabilized by the pressure regulator R2, and then the above-described dilution is performed. In the process, the gas flows through the air supply path 6a on the flow meter Mf3 side through which the air OA flows, and is supplied to the junction B1 as a check gas. Then, the raw material gas G0 is supplied to the branch portion B2 as a gas supply unit for supplying the gas for inspection to the gas introduction unit 72 of the gas inspection device 70 and the supply joint 5a.
Accordingly, when the raw material gas G0 is used as the inspection gas as it is, even when the flow rate of the raw material gas G0 becomes a relatively large flow rate corresponding to the required flow rate of the inspection gas, the raw material gas G0 is used as the inspection gas. In the dilution process, a relatively large flow rate of the air OA is passed through the air supply path 6a corresponding to a relatively large flow rate, and the flow rate of the raw material gas G0 is measured by a flow meter Mf3 corresponding to a relatively large flow rate, for example. can do. On the other hand, the source gas supply path on the side of the flow meter Mf2 through which the source gas G0 having a relatively small flow rate flows in the above-described dilution processing is configured as a relatively simple and small one corresponding to only a small flow rate. As the total Mf2, one corresponding to a relatively small flow rate is used.

  The detailed processing flow of the inspection processing (# S4) in the inspection processing method shown in FIG. 4 has been described above. After the inspection processing (# S4) is performed, the next gas inspection apparatus 70 to be inspected belonging to the same group and belonging to the same group. If there exists (# S5), the gas inspection device 70 to be inspected is changed in the same group, and the inspection process (# S4) is performed on the gas inspection device 70 after the change. At this time, when the inspection gas G1 generated by the dilution process is used, when the inspection target is changed in the same group, the generated inspection gas G1 is temporarily passed through the three-way valves V4 and V5. The dilution process is continued in such a manner that the gas is supplied to the open portion O4 and exhausted. As a result, the concentration stabilization processing and the like when changing the inspection target are omitted, and the time required for the change is reduced.

  When shifting to the inspection process of the next gas inspection device 70 belonging to the same group, a predetermined first cleaning process (# S8) is executed, and the inspection process of the gas inspection devices 70 in the same group is performed. Are completed, a predetermined second cleaning process (# S9) is executed.

[Cleaning process]
In the first cleaning process (# S8) executed when shifting to the inspection process of the next gas inspection device 70 to be inspected belonging to the same group, the atmospheric OA is introduced into the gas introduction unit 72 of the gas inspection device 70 and The gas inspection device 70 is cleaned (hereinafter, referred to as “gas inspection device cleaning”).
On the other hand, in the second cleaning process (# S6) executed when all the inspection processes of the gas inspection devices 70 in the same group are completed, in addition to the gas inspection device cleaning, the inspection gas G1 or the raw material gas which is the raw material thereof The air OA is caused to flow through the gas path through which G0 flows, and the gas path is cleaned (hereinafter, referred to as “gas path cleaning”).
FIG. 12 shows the operating states of various auxiliary machines and the gas flow states when the gas path cleaning and the gas inspection machine cleaning are performed at the same time.

(Gas path cleaning)
Specifically, in the gas path cleaning, the supply of the raw material gas G0 from the gas container C1 is stopped by closing the flow control valve V10 from the state of the gas alarm confirmation processing (# S15) in FIG. The switching state of the three-way valves V8 and V13 is set, and the atmosphere OA taken in from the opening portion O3 is supplied to the source gas path 6b on the flow meter Mf2 side through which the source gas G0 flows in the gas alarm confirmation process (# S15) and the like. Through. Thus, the source gas G0 remaining in the source gas path 6b is replaced with the atmospheric OA, and the source gas path 6b is cleaned.

Further, the atmospheric OA after flowing through the raw material gas path 6b passes through the inspection gas path 6c from the junction B1 through which the inspection gas G1 has flowed through the gas alarm confirmation processing (# S15) to the branching section B2. Flow through. As a result, the inspection gas G1 remaining in the inspection gas path 6c is replaced with OA by the atmosphere, and the inspection gas path 6c is cleaned.
By performing such gas path cleaning, erroneous inspection due to the inspection gas G1 or the source gas G0 remaining in the gas path is avoided in the inspection processing for the next gas inspection device 70 to be inspected. .
In this gas path cleaning, the air OA supplied to the branch part B2 after flowing through the source gas path 6b and the inspection gas path 6c is set via the opening part O4 by setting the switching state of the three-way valves V1 and V5. Exhaust to the outside.

  In the gas path cleaning performed after the gas alarm confirmation processing (# S15) in the case of performing the non-dilution processing shown in FIG. 11, the gas path cleaning is performed in the path through which the source gas G0 flows in the gas gas alarm confirmation processing (# S15). It is desirable to allow atmospheric OA to flow. That is, by setting the switching state of the three-way valves V13, V8, and V12, the air OA taken from the open portion O3 is supplied from the three-way valve V13 to the gas path 6b side, and the air OA is supplied from the three-way valve V8 to the three-way valve V8. The three-way valve 12 is returned to the side of the valve 12 and flows through the air supply path 6a downstream of the three-way valve 12. As a result, in the gas alarm confirmation process (# S15) in the case of performing the non-dilution process, the source gas G0 remaining in the path through which the source gas G0 flows is replaced with the atmospheric OA, and the path is cleaned. Become.

  Further, in the gas path cleaning, when the gas inspection machine cleaning that is performed simultaneously is completed, the switching state of the three-way valve V1 is set, and the air OA in the branch portion B2 is supplied to the three-way valve V1 side. Then, the inspection gas G1 and the source gas G0 remaining in the path from the branch portion B2 to the three-way valve V1 are replaced with the atmospheric OA, and the path is cleaned.

(Gas inspection machine cleaning)
On the other hand, in the gas inspection machine cleaning, the gas supply joint 5a to which the gas introduction unit 72 of the gas inspection device 70 is connected is opened to the opening O1, as in the initial confirmation process (# S12). Atmosphere OA taken from the opening O1, that is, fresh air OA different from that flowing through the gas path is introduced into the gas introduction unit 72 of the inspection machine 70. Then, the atmospheric OA is introduced into the gas inspection device 70 via the gas introduction unit 72, and flows through the sensor unit 76. Thus, the inspection gas G1 remaining in the gas introduction unit 72 and the sensor unit 76 on the gas inspection device 70 side is replaced with the atmospheric OA, and the gas inspection device 70 is cleaned.
The gas inspection machine cleaning ends when it is determined from the output signal of the sensor unit 76 of the gas inspection machine 70 that the concentration of the specific component in the introduced gas has become substantially zero.

By performing such gas inspection machine cleaning, erroneous detection due to the inspection gas G1 remaining in the gas introduction unit 72 or the like is avoided when the gas inspection device 70 is used immediately after the inspection processing.
In this gas inspection machine cleaning, the exhaust EA exhausted from the exhaust portion 77 of the gas inspection device 70 is taken in together with the surrounding air from the opening 59, and is exhausted outside from the opening O4 through the exhaust joint 5b. You. This prevents the exhaust EA from being released from the front surface on the storage section 5 side. Further, the exhaust EA sucked from the opening 59 is exhausted together with the atmospheric OA after flowing through the raw material gas path 6b and the inspection gas path 6c in the gas path cleaning. This simplifies the exhaust path for gas inspection machine cleaning and gas path cleaning.
The exhaust EA and the atmospheric OA may be separately discharged to the outside.

  In the present embodiment, the gas path cleaning and the gas inspection device cleaning are performed in different atmospheres OA. However, for example, the air flowing through the gas path is introduced into the gas inspection device 70 and the like. Cleaning may be performed in the same atmosphere.
