Description

Chromatograph and method of reusing the column

Technical field

The present invention relates to chromatographic techniques, and more particularly to a chromatograph and a method of reusing a chromatography column.

Background technique

Chromatography (also known as chromatography) separation and purification mechanism is based on the difference in the affinity of the two components in the mixture, using the selective distribution of different substances in different phase states, fixed by mobile phase (Mobile Phase) The mixture in the Stationary Phase is eluted, and the different substances in the mixture move along the stationary phase at different speeds, ultimately achieving the effect of separation and purification. The chromatographic process is the process of "dispensing" the molecules of the various components of the mixture multiple times between the mobile phase and the stationary phase. For example, gas chromatography uses a gas as a mobile phase, and liquid chromatography uses a liquid as a mobile phase. In 1903, the Russian chemist M.C. Zwitt first used liquid chromatography for the separation of chlorophyll.

Chromatography is further divided into analytical chromatography and preparative chromatography depending on the application. The purpose of the analytical chromatogram is to analyze the content of one (or several) pure substances in the mixture. The purpose of the preparative chromatography is to obtain a pure substance from the mixture. The process of increasing the injection volume of the analytical chromatogram while obtaining a large amount of the desired substance (fraction) can be referred to as preparative chromatography.

As a specific example, the current Flash Chromatography technology widely used in organic synthesis laboratories belongs to one of preparative chromatography, which was first proposed and refined by W. Clark Still of Columbia University in 1978. Compared with the traditional liquid chromatography separation technology, fast liquid chromatography uses a silica gel column with a smaller particle size to perform rapid separation and purification of the target compound under a certain pressure, and the efficiency is higher. The separation and purification of target compounds using chromatographic techniques is the basic technology and means that every organic synthesis personnel must master and use on a daily basis. Columns of different materials can be used to manually fill the column for separation and purification, or the separation and purification of the compound can be performed using an automated preparative chromatography system and a pre-packed chromatographic column. At present, products based on fast liquid chromatography technology have been widely used in the market. With the development of hardware and software technology, the degree of automation of modern fast LC systems is already very high. Once the separation and purification conditions are determined, the user can perform the separation and purification of the target compound with a simple operation.

However, existing liquid chromatographic separation techniques and their instruments are highly automated, and pre-packed columns are also widely used, including preparative columns and analytical columns. The prior art uses information on columns. Corresponding collection and processing have been carried out, but the prior art cannot effectively process the usage information of the collected columns and further guide the user to better reuse the column. Moreover, the prior art cannot use the information of the same type of column. Analysis and classification, especially for the use of the same type of column separation and purification of one or more target compound systems, lack of evaluation analysis, so can not refine the summary and recommend a model to isolate one or more target compound systems The best way to use it.

Further, when the column cannot be reused and needs to be disposed of, the prior art lacks the establishment and guidance of methods and processes for the targeted disposal according to the history of use of the column.

Therefore, the efficiency of the prior art for the use of the column needs to be further improved.

detailed description

Before explaining the flow of the device structure and method of the present invention, the working principle on which the present invention is based will be described in detail.

The invention is described in detail below with reference to the drawings and specific embodiments. It is to be noted that the aspects described below in conjunction with the drawings and the specific embodiments are merely exemplary and are not to be construed as limiting the scope of the invention.

A column, especially a normal phase column, separates and purifies the same or similar target compound system, and uses the same or similar solvent system to more efficiently reuse and extend the number of reuses. The invention records and uses the information of the column to guide the user to more effectively reuse a column for the separation and purification of the same or similar target compound system.

The invention uses the Internet technology to separate and purify the usage information of one or more target compounds by collecting and processing the chromatographic columns provided by different users, and classifying and evaluating the collected usage method information, and then giving a current model. Information on the best use of one or more target compound systems by column separation and purification. Moreover, users can optimize the existing best usage information, develop more efficient usage information for this type of column and upload and update the application information of this type of column for other users to use for maximum use. Or reuse the effect of the column.

The application information for one type of column is a collection of information on the use of one or more target compound systems for all types of columns. The information on the method of use of the column can be classified based on the information of the target compound system purified and purified by the column. The use of the same classification of the column The method information can be prioritized by evaluating the efficiency value after an evaluation system, and the usage information information with high evaluation efficiency value is preferentially recommended to the user. The evaluation system is determined by the following parameters: the efficiency of the separation and purification process, the number of actual reuses, and the cost of column cleaning regeneration.

When the user uses the liquid chromatography apparatus of the present invention to separate and purify a target compound system (ie, a mixture or a sample), the first and the same target compound system can be repeatedly purified by the information retrieval of the target compound system. The column used, if a matching reusable column is retrieved, it is preferred to use a matching reusable column. Further, when the user selects the column used for the separation and purification, the application information of the matched column of the same model is retrieved, and if the application information of the matched column is retrieved, the application information of the column is preferentially recommended by the user. The best way to use information.

If no matching reusable columns are retrieved, and/or no matching column application information is retrieved, then after the user completes the separation and purification of the target compound system, the column usage information is recorded and saved, and When the column cannot be reused again, according to the authorization of the user, the usage information is extracted from the usage information of the column, and after evaluation, the application information of the model to which the column belongs may be uploaded and published to the central database. And for other users to get used.

When a column cannot be reused again, the user can dispose of the column based on the matched column disposal information, minimizing environmental impact. If the scrap disposal information of the matched column is not retrieved, the liquid chromatography instrument of the present invention guides the user to the scrap disposal of the column, and uploads to the central database according to the user's authorization to apply to the model of the column. The scrapping process for adding new columns to the information is available to other users.

The method information may include, but is not limited to, information of the target compound system, information on separation and purification process, or information for obtaining information on the separation and purification process, process information of column cleaning and preservation after separation and purification, and scrapping of the column. Disposal information, as well as information on the actual number of reusable times when this type of column is used to separate and purify one or more target compound systems.

The application information of the column can be classified according to the information of different target compound systems, and each method of use information has corresponding evaluation efficiency. The evaluation efficiency value of the same classification method of the column is determined by at least the following parameters: the efficiency of the separation and purification process and the number of actual reuses, and the cost of column cleaning regeneration, wherein the efficiency of the separation and purification process includes recovery of the target compound. Rate, material cost, and time cost.

4 is a schematic diagram showing the application information of a type of chromatography column sorted according to different target compound systems and sorted according to the evaluated efficiency values of the use method information, according to an aspect of the present invention.

Each specific column of each model can separate and purify different target compound systems, resulting in different usage information. Each method of use information corresponds to a particular target compound system. Thus, these methods of use information can be classified according to the target compound system.

As shown in FIG. 4, a plurality of usage method information for processing a target compound system 411 is classified into one class, including using method information 411-1, 411-2, ... 411-n; and processing another target compound. The plurality of usage method information of the system 412 is divided into another category, including usage method information 412-1, 412-2, ... 412-n; and a plurality of usage method information for processing another target compound system 41m is It is divided into another m class, including usage method information 41m-1, 41m-2, ... 41m-n.

In addition, for each category, the usage information of the classification can be sorted according to the efficiency value. Therefore, when the user needs to use a specific column to perform purification separation of a specific target compound system, the application information of the column in the central database can be retrieved, specifically, the application information corresponding to the model number of the column is found, and the application information is searched for. The usage method information corresponding to the classification of the specific target compound system is further recommended to the user for the purification separation from the usage information information of the classification.

Application information can be extracted from the usage information of the column of the database module 111 of each instrument 11, and the application information can be uploaded to the central database 101 for sharing by all users who can access the central database 101. In other embodiments, the database module 111 of the instrument 11 can also be in data communication with the central database 101 to obtain application information for the column.

In the present invention, the instrument 11 can include a column management module 114 for primary use management of the column. Specifically, the column management module 114 may include an analysis unit 1141, a matching unit 1142, and a database operation unit 1143.

When the user needs to perform a purification separation of a particular target compound system, the information of the target compound system can be entered, for example, via a user interface on the terminal device 12. After receiving the information of the target compound system, the control unit 1121 instructs the matching unit 1142 to retrieve the usage information of the column in the database module 111 based on the information of the target compound system input by the user to recommend a reusable column to the user. Here, a reusable column refers to a column that has been used to separate the same or similar target compound system. For example, according to the information of the target compound system input by the user, it is known that it is desired to separate and purify the target compound system A, and the matching unit 1142 retrieves the usage information of the column in the database module 111 to find out whether there is a separation or separation used for purification or Similar to the column of the target compound system A. If such a column is present, recommend such a column to the user, so as to recommend the user to use the reusable column that has been used to maximize each of the columns. Use efficiency of the column and avoid potential cross-contamination of the target compound.

In addition to inputting information of the target compound system, the user can input, for example, user information, separated and purified item number information, and the like. In the usage information, the user information, the separated and purified item number information may be associated with the information of the target compound system, so that the matched column can be retrieved and recommended to the user by the user information and the separated and purified item number information. In particular, in the case where the user inputs user information and separate and purified item number information, the column that the user has used may be recommended first.

The reusable column recommended by the matching unit 1142 may be one or more, from which the user can select. In addition to the reusable column, the matching unit 1142 can also recommend a suitable new column. For example, the matching unit 1142 can be based on the information of the target compound system input by the user, specifically based on the TLC (data of the thin-layer chromatography plate, such as R _f value) information of the target compound system (ie, mixture or sample), and the total sample amount. To calculate the appropriate new column to recommend to the user. Of course, the matching unit 1142 can first recommend a reusable column, and in the absence of a cocoa-recyclable column, recommend a suitable new column. Users can select the recommended reusable column or the recommended new column according to their needs, or use the other columns of their choice without selecting the recommended column. If a reusable column is used, the user finds the column based on the information on the storage location in the column usage information and installs it into the column module 113.

After the user selects the column, the column management module 114 can read the unique number information of the column, and retrieve the production/factory information of the column and the usage status of the column according to the read number information in the database. information. If the acquired column usage status information is not in use and the column is installed in the column module ready for separation and purification of this target compound system, the column information is added to the database module. If the usage status information of the column is the used state, the usage information of the column is further acquired and the related operation is performed by the control unit 1121. The related operation of the control unit 1121 includes: if the column is mounted on the column module 113, the control unit 1121 compares the information of the column required for the current separation and purification process selected by the matching unit 1142 and the acquired column mounted module. The information of the column, if the information is consistent, continue the separation and purification process flow. If the information is inconsistent, the control unit 1121 prompts the user to install the wrong information of the column and selects the correct installation. The column is in the column module 113. If the column is not yet installed in the column module, the control unit 1121 can display the column acquired in the database on the display device of the instrument 11 or the mobile terminal device or other terminal device linked to the instrument 11 via the network. Relevant usage information, including information on the most recent target compound system, solvent system information, and user information.

After the user selects the column to be used, the matching unit 1142 may further retrieve application information of the matched column of the same model from the central database 101 based on the column selected by the user, so that the execution unit 1122 uses the user-selected The column and the matching application information are manipulated accordingly.

Specifically, the matching unit 1142 may retrieve application information of the column in the central database 101, and find application information about the column of the model selected by the user, wherein the usage information in the application information is based on the target compound. If the system is classified, the most efficient method of use information can be recommended to the user from the usage information of the classification of the target compound system to be separated and purified. Of course, all the usage information of this category can also be recommended to the user, and the user can choose it. The user can select the usage information in the recommended application information, or use the recommended usage information to perform purification and separation according to the designed process.

The operations performed by the execution unit 1122 using the user-selected column and the matched application information may include a separation and purification process of the target compound system, a cleaning and regeneration storage process of the column, and a waste disposal process of the column. Of course, in the case that the user does not select the matched recommended application information, the execution unit 1122 can also perform separation and purification, column cleaning and regeneration preservation, and end-of-life disposal process according to the user-designed process flow.

For example, the first execution unit 1122 can perform a separation and purification process of the target compound system according to the separation and purification process information in the recommended usage method information. After performing the separation and purification process, the execution unit 1122 can also generate separation and purification process information of the separation and purification process. The database operating unit adds information about the usage of the used column to the database module 111 based on the newly generated separation and purification process information or updates the existing usage information about the used column.

After performing the separation and purification process, the analysis unit 1141 determines whether the column is still in use based on the usage information of the column and the user setting. If the user setting indicates that the cleaning regeneration process is not required, or the cost of the cleaning regeneration is estimated to be greater than the cost saved by the column reuse again based on the usage information about the column, it is judged that the column is no longer used.

If the column still needs to be used, the indicating unit 1141 can perform the cleaning and regeneration saving process of the used column according to the column cleaning and saving process information in the recommended usage information. After the cleaning regeneration save process is performed, the execution unit 1122 may generate flow information about the current wash regeneration save. Correspondingly, the database operation unit 1143 may add usage information about the used column to the database module 111 based on the newly generated flow information of the cleaning regeneration and save the existing usage information about the used column. .

If the column is no longer in use, the execution unit 1122 can perform a waste disposal process for the used column based on the waste disposal information of the column in the recommended usage information. Execution of the scrap disposal stream After the process, the execution unit 1122 may generate the scrap disposal information of the scrap disposal. The database operating unit 1143 may upload the newly generated scrap processing information to the database module 111, the networked other database module 111, and the central database 101 for sharing.

If the column is no longer used, the analysis unit 1141 can extract usage information about the column from the usage information of the used column stored by the database module 111 and other networked module modules. The database operating unit 1143 may upload the extracted usage method information to the central database 101 based on the user authorization to update the application information of the column of the model of the used column.

Preferably, the database operating unit uploads the extracted usage method information based on the user authorization only when the evaluation efficiency is superior to the usage information of the same classification of the existing same type of chromatography column. For example, an update is uploaded when the extracted usage method information is evaluated to be more efficient than the highest efficiency usage information in the same classified usage information of the existing same type of chromatography column.

Since even if the user operates according to the application information recommended by the matching unit 1142, it is possible that the user separates and purifies the same or similar target compound system using the separation column (for example, some parameters of the mixture are different from the existing ones). ), if there are slight changes or "optimizations" to the process (or existing separation and purification methods), then a better situation will occur.

From the design point of view, for example, the same target compound system, but because of the synthesis process or the influence of some variables in the post-treatment of the mixture, it will result in the content of the components of the target compound system (ie, the mixture). Different, which leads to some minor changes in the separation and purification method. If each user can “exhaust” these changes in multiple operations, then in theory, the future users will always find the highest efficiency when they encounter this target compound system. How to use it.

Moreover, in order to encourage users to use reusable columns that have been used as much as possible to save resources, the user information in the database module 111 includes the number of times the column used by the user and the user account information. Each time the user uses the column, the database operating unit 1143 may newly add or update the user's information on the number of times the column is used, depending on the situation in which the new column is used or the old column that is reused. The user's account information is updated accordingly. For example, each time you reuse an old column, you can increase the balance in your account information to create an incentive mechanism that encourages users to reuse the column.

In Figure 1, each organization, such as each laboratory or company, has an instrument 11 to which each instrument 11 can be connected. The usage information of all the local columns is stored in the database 111 of the instrument 11 inside each organization, and the application information of various types of columns is stored in the central database 111. Of course, the database 111 of the instrument 11 can also be in data communication with the central database 111 to obtain the application information.

When the user wants to perform the purification separation of the target compound system, the user can query the usage information of all the columns in the database module 111, and can know the usage of all the available columns in the local area, so that the user can recommend a reusable column. If such a column is available, recommend such a column to the user, so that it is recommended to use the reusable column that has been used to maximize the possible The efficiency of each column.

Once the user has selected the column, the central database 101 can be queried to find the optimal usage information for the column and the target compound system across the network to improve purification separation efficiency.

2A and 2B show a flow chart of a method of guiding a user to reuse a chromatography column in accordance with an aspect of the present invention. As shown, the method can include the following steps:

Step 21: The user enters information that requires separation of the purified target compound system.

Information on the target compound system can be used to characterize and distinguish a target compound system, ie, a mixture or sample, including characteristic information of the target compound system, and/or TLC (thin-layer chromatography plate) information of the target compound system, ie, the mixture or sample, and/or Mass spectrometry information, etc. When the characteristic information of a target compound system is missing or cannot be disclosed, the information can distinguish a target compound system.

In addition to information on the target compound system, the user can also enter user information and/or separate and purified item number information.

Step 22: The matching unit 1142 retrieves the matched reusable column information in the database by using the obtained information and/or separates and purifies a suitable new column for the user according to the information of the target compound system.

Step 23: If the information of the matched reusable column is retrieved, step 231 is further performed to determine whether to select a matching reusable column, and if a matching reusable column is selected, the step is performed. twenty four. If no information is found for the matching reusable column, proceed to step 25.

Step 24: The control unit 1121 selects to use the matched reusable column for separation and purification based on the user's instruction.

Step 25: The control unit 1121 selects and selects a suitable new column recommended by the matching unit 1142 or a column selected by the user based on the user instruction for separation and purification.

Step 26: The matching unit 1142 searches the database for the application information of the same or similar target compound system for separating and purifying the same type of chromatography column matched with the selected column.

If there is matching application information of the column, the control unit 1121 prompts the user to preferentially select the used method information in the matching application information of the column, so as to include the sample loading and the loading according to the separation and purification parameter information in the usage method information. The setting of the separation and purification process parameters is performed, and after the execution unit 1122 ends the separation and purification process, the control unit 1121 prompts the user to preferentially select the column cleaning and preservation process in the application information to perform the cleaning of the column. And save, of course, this is in the case of judging that the column can continue to be used.

Preferably, the most efficient usage information in the application information can be recommended. However, the user may select the recommended usage information or may not select the recommended usage information, but design the corresponding process.

Step 261: Execution unit 1122 performs this separation and purification.

The execution unit 1122 may perform the separation and purification according to the separation and purification process information in the recommended usage method information selected by the user, or may also be performed according to the self-designed separation and purification process setting.

After the separation and purification are completed, the control unit 1121 instructs the column management module 114 to perform corresponding operations.

Step 262: judging whether the column needs to be cleaned and regenerated according to the setting of the user's separation and purification and the cost of the expected/calculated process flow of the cleaning regeneration.

If it is determined that cleaning regeneration is not required, step 263 is performed; if it is determined that cleaning regeneration is required, step 264 is performed.

Step 263: The column management module 114 recommends the information of the column rejection process to the user, and the user performs the disposal of the column, and step 265 is performed.

The execution unit 1122 scraps the column according to the recommended scrap process or the self-designed scrap disposal process, and generates corresponding scrap disposal information. The database operating unit 1143 may perform a new or update operation on the usage information of the column.

Step 264: The control unit 1121 instructs the execution unit 1122 to perform a cleaning and regeneration process of the column. Generate process information for the cleaning and regeneration of the column.

The execution unit 1122 performs cleaning and regeneration of the column according to the cleaning and regeneration process in the recommended application information.

Step 265: According to the user authorization, the analyzing unit 1141 extracts the usage method information from the usage information of the column, and after uploading and evaluating, may upload and publish to the database 02.

Preferably, the database operating unit 1143 uploads the extracted usage method information based on the user authorization only when the evaluation efficiency is superior to the usage information of the same classification of the existing same type of chromatography column.

Step 266: The database operation unit 1143 performs a new or update operation on the usage information of the column used this time.

Step 267: The database operation unit 1143 performs a new or update operation on the user information of the user of the current operation.

3 shows a flow chart of a column rejection process in accordance with an aspect of the invention. As shown, the process includes the following steps:

Step 31: Determine if the column can continue to be reused.

At the end of the separation and purification process, the column management module can determine whether the column can continue to be reused based on column usage information and/or user settings.

For example, if the user setting indicates that the cleaning regeneration process is not required, or the cost of cleaning regeneration is estimated to be greater than the cost saved by the column reuse again based on the usage information, it is determined that the column used is no longer used.

Step 32: Determine whether the column can continue to be reused. If it can be reused, go to step 33. If it cannot be reused, go to step 34.

Step 33:

Flow

264, 266, 267 is performed.

Step 34: Perform a column rejection process.

Step 35: The column management module 114 retrieves application information for the matching column of the database.

If there is a matching column application information, that is, the column application information includes the column The process information of the disposition process is performed, and step 36 is performed; if there is no matching application information of the column, the process 351 is performed.

The retrieval matching process herein may be the retrieval matching process in the process 23, or may be a new retrieval matching process independent of the process 23.

Step 351: Further search for the scrap disposal information in the application information of the similar type of column of the matching target compound system in the database 02. If there is a matching result, step 36 is performed, otherwise step 352 is performed.

Different types of columns can be used to separate and purify the same target compound system. For example, small sample columns separate and purify small samples due to different sample sizes, while large size columns separate and purify large samples, if large size If the application information of the column on the target compound system has not been scrapped, if the application information of the small-sized column on the target compound system has relevant scrap information, when the large-sized column is scrapped, Retrieve the scrap information for a small-sized column as a reference.

Step 352: Guide the user to execute the scrap disposal process:

1. According to the history of the target compound system separated and purified by the chromatography column, it is searched whether there is a special treatment requirement of the relevant compound in the database 02;

2, generally use a strong polar solvent to wash the column until the sample has no residue or the impact can be ignored, record the solvent type and proportion, flow rate and rinse time and other parameters;

3. Remove residual solvent from the column, such as using compressed air or a small air pump;

4. The waste liquid collected in the scrap disposal process is disposed of according to relevant regulations and forms a record;

5. The scrapped column after solvent removal is recycled by a special mechanism. The basic process of the recycling process is to decompose the scrapped column into the column body and the column packing, and then separately process the solid waste according to relevant regulations;

6. The execution unit 1122 generates a column scrap disposal process information.

Step 353: Upload the scrap disposal process information.

After the user authorizes the analysis and evaluation by the analyzing unit 1141, the scrapping process information of the column generated by the executing unit 1122 can be uploaded to the database 02 for use by other users, for example, added to the application information of the type of the column in the central database. . Alternatively, scrap disposal process information can be added to the column usage information for extracting usage information and uploading it to a central database for sharing.

Step 36: The user is recommended to use the scrapped disposal process information of the matched column to perform the waste disposal process of the column. The user can directly use the matching scrap disposal process, or optimize according to step 352 according to the matched scrap disposal process, and then perform step 353.
