Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel analysis system that combines an analysis device such as a gas chromatograph and a data processing device used therein.

A conventional chromatograph data processing device receives an analog signal from a chromatograph and converts this signal into an A/D converter.
We perform data processing such as converting the data, determining the peak area, and then performing quantitative calculations.

Further, a more advanced data processing device is capable of performing the above data processing and at the same time controlling part of the chromatograph, such as switching columns using a time program or the like.

Generally, a data processing device and an analysis device such as a chromatograph are manufactured separately, and each performs its respective functions independently.

The present invention provides that by combining a data processing device and an analysis device, which are generally separate, it becomes possible to mutually utilize the functions of both, thereby creating a higher performance analysis system. This was done with a focus on what could be achieved.

By the way, in order to obtain such an analysis system, the two systems are connected by a transmission controller so that information such as data can be exchanged between the two systems. A case that can easily be considered is
This is a case in which both devices are designed after exchange information such as data formats and exchange procedures between the two devices is determined in advance. However, the biggest problem in such cases is that once you have designed an analysis device, if you design another analysis device in the future, you will have to combine the criminal analysis device with the previously designed data processing device! This means that it is completely impossible to deal with the newly exchanged information that would be required by the new analyzer without modification. That is, a problem arises in that a previously designed data processing device cannot be used as is for a newly designed analysis device.

As a way to deal with this problem, the exchange information request contents (for example) from the analyzer side (name of parameter, format, upper and lower limits of set value, name of command, format, etc.) are sent to the data processing device side. The data processing device stores the request contents in a predetermined memory, and also stores the corresponding exchange information contents (operator settings such as parameters, commands, etc.) based on the request contents. There are ways to ensure that. Therefore, according to this method, it is possible to cope with other analytical devices that may be designed in the future. However, even with this method,
It is necessary for the data processing equipment side and the analysis equipment side to discuss the format of the requested exchange information in advance, and it is virtually impossible to respond to every analysis equipment that will be designed in the future. Furthermore, this method has a major drawback in that extra memory must be reserved for the exchange information as described above.

Furthermore, as another method to deal with the above problems, RASI
Using a language such as C, the I10 board can be directly operated by a BASIC program using commands such as 1N (input command) and 0UT (output command) to interact with the analyzer, making it more versatile and capable of being developed in the future. It is also possible to consider a method that corresponds to the analysis equipment that may be available. However, this method has the major disadvantage that it is necessary to assemble a complex program that involves quite complicated steps, and that it is difficult to understand the correspondence between the program and the parameter names.

Furthermore, this method also has the disadvantage that, like the above-mentioned method, it is necessary to decide in advance the procedure for exchanging the monitor with the analyzer.

An object of the present invention is to provide an analysis system that is more convenient and has better performance without the drawbacks of the above-mentioned methods.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the configuration of an embodiment of the present invention,
0) is the analyzer (for example, a gas or liquid chromatograph), (the data processor is the data processor, (the river is the transmission controller on the analyzer side, (2+1 is the transmission controller on the data processor side, (3) is (1) Cable connecting (2) and +4
[, CRT, +5) is a cassette memory. The analysis device (1) and the data processing device (2) each have separate microcomputers built in, so that they can each operate independently. In addition to general data processing functions such as peak area integration and quantitative calculation, the data processing device (2) has P? It has an interpreter (22) for ASIC language as firmware, and by programming this program in BASIC language, the performance of the device can be expanded arbitrarily. When extended for transmission, special languages can also be translated.On the other hand, the analyzer (1) side also has a simple interpreter that deciphers this special language for transmission, which allows for the combination of the two. For example, if there is a parameter called FLOW on the analyzer (1) side, the data processing device (2) side does not have a parameter key called FLOW for that analyzer (1). Also, from the data processing device (21 side) keyboard (not shown) (which has keys for alphanumeric characters and various symbols like a typewriter key), F tow + 1 is input.
= A * 2 (can also be incorporated into the BAS IC program) and the key human power is the data processing device (fine interpreter 2) from the # symbol to the external device (in this case, the analyzer (1) Since it is judged that it is the execution part (in this case, the assignment statement of the parameter FLOW), if the right side of the expression is calculated and the answer is 2..5, /FLOW-2
,,51 character strings are sent to the external device @(analyzer (1)).

The interpreter (121) of the analyzer (1) translates this and determines that 2.5 has been sent as the value of the FLOW parameter, so it sets 2..5 to FLOW so that it is greater than or equal to 1. This allows you to easily set the parameters of the analyzer (1) from the data processor (2) side.At this time, when data is received from the analyzer (1) side to the data processor (2) side, However, if the interpreter on the analyzer (1) side [1 (7)] sends information that does not meet the standards, or if there is a mistake such as the setting value exceeding the upper or lower limit, an error message will be sent. Since the information is returned, the data processing device (2) side can display an error. In this way, the data processing device (■ side) returns the analysis device (
Name of the parameter on the υ side.

There is no need to be concerned with the format, upper and lower limit values, etc., and there is no need to make error judgments regarding these settings.Also, since FLOW1=A*2 has a format similar to a general BASIC statement, the parameter It is easy to correspond with the name FLOW, and it is also easy to operate. Similarly, on the data processing device (2) side, PUMP#1==1. PUMI'M1=
By operating =O, PUM on the analyzer (1) side
You can perform the same operation as turning the P operation key on and off.

This can be done freely from the management device (2) side. Furthermore, as another example, suppose there is a parameter TEMP on the analyzer 0) side, and the temperature is controlled to the set value, then A = TEMPf # 1 on the data processing device (2) side. *2 By manually inputting the key, the data processing device (identifies that the signal is a call to an external variable, sends the string 'TEMP' to the analysis device (1), requests the value of the parameter, and performs the analysis. The device (1) side translates the sent characters and sends the parameter value of TEMP back to the data processing device (2) side, which is multiplied by (sense) and assigned to the variable A.

Similarly, on the data processing device (2) side, B=TEMP
When you press the key 01M manually, there is a letter M, so it is determined that it is a request for an actual measurement value, and the temperature (TEM) is sent from the 1 analyzer (1) side.
The actual measured values of P) are sent to the receiving device (B), and various data from the analytical device (υ side) can be sent to the receiving device (B). The values of A and H above can be printed out or displayed on the CRT (41).The data sent from the analyzer (1) can be 6 for BASIC language user variables with names such as
=x, so you can freely process it later.

As described above, according to the present invention, although the data processing device (2) side does not have any information such as the parameters and commands of the analysis device (1) side, it is easy to analyze data from the data processing device (side). You can set parameters and operate keys on the device (1) side, and call the parameter values and actual measured values of the analyzer (υ side) to the data processing device (1) side to perform free processing such as printing and calculations. can.

Furthermore, according to the present invention, there is no need for the data processing device (2) to have any information from the analysis device (1), so that the above-mentioned transmission is possible even in the analysis device (1) that will be developed in the future. It has the advantage that if it is equipped with a dedicated interpreter θ and a transmission controller, it can be handled without any problems.

As described above, according to the present invention, data can be freely exchanged between the analysis device (1) and the data processing device Q), so the functions of both can be used effectively and the analysis can be carried out. The functionality of the system can be significantly increased.

FIG. 2 is a final example showing the effects of the present invention.

Reference numbers 2 to 5 in FIG. 2 are the same as reference numbers 2 to 5 in FIG. 1. *Qy is a liquid chromatograph, (6)
is an ultraviolet absorption photodetector whose wavelength is controlled by a liquid chromatograph (ly).The program for this analysis system is written in the BASIC language.
It is stored in the cassette memory (5). When the program in the cassette memory (5) is loaded into the data processing device (2) and the 7° program is run, the data processing device (2) first sends a liquid chromatograph (1γ nihara meter) to the liquid chromatograph ( Parameters such as analysis conditions for 1γ are automatically set. Next, the wavelength of the ultraviolet absorption photometer (6) is determined through the data processing device (by the RASIC program installed in the liquid chromatograph)'. Scanned with 200 fins and 3501111 at L5su+ intervals.

The output (absorbance) of the detector (6) at this time is sent to the data processing device (2) and stored in the memory of the data processing device (■.The data (baseline) at this time is shown in Figure 3 (horizontal). The first-order liquid chromatograph (graph with detector wavelength on the axis and amplitude on the vertical axis) fluctuates greatly,
A sample is injected into γ, and when the data processing device (2) detects the top of the component peak, the pump is stopped to stop the flow of carriers. Then, the wavelength of the detector (6) is scanned in the same manner as described above. The data at this time, as shown in Figure 4 (a graph where the horizontal axis is the detector wavelength and the vertical axis is the amplitude), shows that the component peak is superimposed on the 1 of the large baseline fluctuation, which is different from the true absorbance curve. It's different and very hard to see.

Since the data processing device (2) has memorized the baseline in Fig. 3, the data in Fig. 3 is subtracted from Fig. 4 and the true absorbance as shown in Fig. 5 is displayed on the printer plotter on the data processing device (2) side. You can get a curve. In this way, with the liquid chromatograph (1)' alone, it is only possible to obtain absorbance curves with large fluctuations in the baseline. A curve can be obtained.The liquid chromatograph (1) does not have a cassette memory, but as mentioned above, the liquid chromatograph is stored in the data processing device (0 side cassette memory (6)). All the analysis conditions for graph o)′ and the program for analysis can be stored and used in the data processing device (■) as needed.Moreover, the liquid chromatograph (1γ is the data processing device ( 2) Can be automatically controlled by the RASIC program on the side.Also, liquid chromatograph (
The lγ does not have a CRT display function, but the liquid chromatograph (1γ side parameters, actual measured values, etc.) can be displayed in the data processing bag @ (
2) It can be displayed arbitrarily on the CRT +4). In this way, the liquid chromatograph (1γ) can effectively utilize the functions of the data processing device (2).

A data processing device (or up to four various analytical devices (υe (1
) Can be combined with s... In FIG. 6, parts corresponding to those in FIG. 1 are given the same reference numbers. In this case, each analyzer is distinguished from each other by the number after #. For example, the previous FLOW #1 is the first analyzer, and FLOW #2 is the second analyzer.

Furthermore, as in still another extended embodiment of the present invention shown in FIG. 7, a pure white data processing device (2), .
It can be connected to another data processing device (2)' and used for organizing data, supporting other data processing devices, etc. In this way, the analysis system of the present invention is highly extensible.

Note that in the above-mentioned extended embodiment, the RASIC language is used, but any interpreted language may be used.

As detailed above, according to the present invention, an analysis device and a data processing device can be combined in a relatively simple manner, and as a result, a highly versatile and advanced analysis system can be obtained. The effect is profound.
