Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to chromatographic analysis, and particularly to a chromatographic data processing device suitable for processing quantitative calculations of analysis results.

[Conventional technology]

Conventional chromatography data processing devices also have the ability to combine with analytical instrument controllers and autosamplers to configure an automation system and perform automatic analysis. and,
They are also now equipped with the ability to store data from analysis results.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, automatic storage is performed as a method of storing analysis data, but no consideration is given to the means of using the data, and there are problems with the automatic calculation method.

The present invention has a function of creating an automatic calculation program,
The purpose of this is to perform automatic and unmanned analysis calculations.

[Means to solve the problem]

The above objective was achieved by equipping the data processing device with a storage that stores data obtained through automatic analysis, a clock mechanism that measures the programmed time, and a trigger mechanism that commands the start of calculation at the set time. be done.

[Effect]

(1) In order to analyze multiple different samples, prepare a large number of files that summarize analysis or calculation conditions.
Calculations can now be ordered.

(2) In order to order the analysis, we prepared a table of analysis columns with clear analysis types.

(3) We have prepared an analysis reservation table for reserving analysis times and a clock function that can display the time.

By providing the above-mentioned technical means, the chromatographic data processing device performs analysis in a predetermined order, and performs necessary calculations as and when necessary, allowing the data processing device to It is possible to perform calculations using free time (time not analyzed). Therefore, it is possible to improve measurement efficiency.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. 1 is a data import unit (A/D converter), 2 is a peripheral device connector,
3 is a control command storage, 4 is a signal data storage, and 5 is a parameter storage such as measurement conditions.

6 is a time advancer, 7 is a central processor, and 8 is an output device.

9 is a control command device, 10 is a display, 11 is an analysis order designator, 12 is an analysis time designator, 13 is an analysis order storage, and 14 is an analysis time storage. The output signal from the analytical instrument passes through 1 A/D conversion section.

It is converted into a digital signal and passes through the second peripheral device connector.
The signal passes through the central processor 7 and is stored in the signal data storage unit 4. At this time, processing is performed in a predetermined format set by the control command unit 9 and according to instructions from the control command storage unit 3. Further, the conditions and the like at that time are stored in the parameter storage unit 5. On the other hand, when signal data is stored in the signal data storage device 4, the signal can also be recorded in the output device 8.

When the clock 6 receives a certain time, it continues to move forward like a clock, starting from that time. When the analysis is completed, the calculation results are printed on the output device 8 in a predetermined format. The explanation so far has shown the operation of one analysis, but depending on the analysis content, the analysis time may be long, and therefore the time to print the results may also be considerably long.If there are a large number of samples, it may take -days of work time. There are cases where you cannot do it. In the present invention, in consideration of this point, prior to analysis, the control command unit 9 specifies the operation for storing the analysis data and stores it in the signal data storage unit 4. , memorize each analysis and assign a memory number.

The analysis order designator 11 instructs recalculation of the stored signal data, and furthermore, the order of calculation is designated by the storage number assigned at the time of storage, and is stored in the analysis order storage 1-3. On the other hand, the analysis time designator 12 predicts in advance the time when all analyzes are completed and storage of signal data is completed, determines the recalculation start time, and stores that time in the analysis time storage 14. When the time advancer 6 becomes equal to the time in the analysis time storage 14, the stored data is recalculated in sequence according to the analysis order 13.

The results are printed as chromatograms and results by eight output devices for each signal data. The above processing will be explained according to the flowchart shown in FIG. The angle of 10° is based on 1 in FIG. 1 for signal acquisition. 101 checks whether the analysis is finished, and if it is finished, 102 (7) signal de.

- Store evening. (4 in Figure 1) If not completed, continue the analysis. Step 103 determines whether all analyzes (number of samples to be measured) have been analyzed. If not completed, the next sample is designated (104) and the analysis of the next sample is started at 105. If the process is completely completed, it is determined in step 106 whether automatic recalculation is specified, and if not, the analysis is completed. If yes, look at the calculation time in 107.

It waits at 108 until that time. When the time comes, recalculation processing is performed in 109 and a report is created.

At step 111, it is determined whether recalculation has been performed for all samples, and if not all have been completed, the next stored data number is designated and recalculation processing is performed. When the process is completely completed, the data processing device is also automatically stopped (112).

[Advantageous Effects of the Invention] According to the present invention, a recalculation program can be created by utilizing the idle time of the data processing device, so that the efficiency of measurement (analysis) can be improved. Moreover, the operation, which normally requires a human being nearby, can be performed unattended, which has the effect of saving labor costs.
