Abstract

PURPOSE:To permit easy changing of condition setting by executing an analysis process according to various analysis conditions set in an analysis condition setting and memorizing means during mounting or after removal of a memory card. CONSTITUTION:A reading part 7 for mounting an IC memory card 8 (8a-8d) is provided on a data processor 3. The card 8 is mounted on the reading part 7 in the case of setting the various conditions of a gas chromatograph body 1, an autosampler 2 and the data processor 3. The cars 8 are provided for each of samples. A program is run in the processor 3 and the analysis conditions stored in the card 8 are read by the memory means in the processor 3 when the card 8 corresponding to the sample to be analyzed is mounted on the reading part 7. All the analysis conditions of the processor 3, the body 1 and the sampler 2 are then changed to the contents stored in the card 8. An operator is, therefore, merely required to start a chromatograph 1 after inserting the card 8 into the reading part 7 and the analysis is thereafter automatically progressed and the conditions are changed without producing errors.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a network type chromatograph that is configured as a system consisting of a gas chromatograph main body, an autosampler, a data processing device, etc. This invention relates to a chromatograph that allows easy setting of analysis conditions.

(B) Conventional technology For example, a conventional network type gas chromatograph, as shown in FIG. 3, has a gas chromatograph body 31,
The autosampler 32 and the data processing device 33 are combined to form a system, and each is provided with each condition setting section 34, 35, 36, and each condition setting section is used to set each condition necessary for analysis processing. Settings were made by operating the keys No. 34, 35, and 36, and also when changing the condition settings, each time the settings were made by operating the keys on the setting section.

(c) Problems to be Solved by the Invention As mentioned above, in conventional gas chromatographs, various conditions are manually set depending on the sample. These various condition settings are so important that they affect the quality of the analysis results, and accurate settings are required. However, even in normal analysis, there are 50 to 60 setting items.
There is no doubt that it is necessary to set these conditions, but as mentioned above, in conventional gas chromatographs, the problem is that it is very troublesome and complicated to set the conditions, rather than setting them by key operation. there were. In particular, there is a risk of erroneous operation for beginners. In particular, when changing temperature conditions for each sample without changing columns, as in recent capillary gas chromatographs, the importance and precision of setting conditions is required. Therefore, an important requirement for future chromatographic devices is how easily conditions can be set.

In view of the above, an object of the present invention is to provide a chromatograph that can easily set analysis conditions for a wide variety of items.

(d) Means and operation for solving the problems The chromatograph of the present invention includes a memory card for storing various analysis conditions of the chromatograph body, data processing device, etc., and when this memory card is installed, the memory A memory card reading means for automatically reading the memory contents of the card, and an analysis condition setting storage means for storing various read analysis conditions and retaining the memory even after the memory card is removed, while the memory card is being inserted. Alternatively, after sampling, analysis processing is executed according to various analysis conditions stored in the analysis condition setting storage means.

In this chromatograph, various analysis conditions for the chromatograph itself, data processing device, etc. are written and stored in the memory card in advance, so when performing analysis processing,
Simply insert this memory card into the memory card reading means, and the contents of the memory card will be automatically read as it is inserted.
It is read by the reading means, and its contents, that is, the analysis conditions, are stored in the analysis condition setting storage means. Based on the stored analysis conditions stored in the setting storage means, analysis processing is executed while the memory card is inserted. Further, even after the memory card is removed, the analysis conditions are retained and stored, so that subsequent analysis processing can be executed based on the stored conditions. The various analysis conditions written on the memory card are automatically stored in the analysis condition setting means each time the memory card is inserted into the memory card reading means during analysis processing. There is no need to perform any operations, and even when changing settings, you can easily change the settings by installing a memory card that stores the different conditions for which you want to change the settings. It becomes possible to set analysis conditions covering a wide range of conditions.

(E) Examples The present invention will be explained in more detail with reference to Examples below.

FIG. 1 is a schematic diagram of a system in which the present invention is implemented. In Figure 1, the system consists of a gas chromatograph main body 1, an autosampler 2, and a data processing device 3, and these devices are mutually configured into a network through a current loop interface (or R3-232C) 42, ↑. , is configured to allow data to be exchanged.

Further, the chromatogram from the gas chromatograph main body 1 is sent to the data processing device 3 via a signal line 5. This data processing device 3 is a device that receives the chromatogram from the gas chromatograph 1 and performs predetermined analysis processing.
This data processing device 3 itself has conventionally well-known functions.This data processing device 3 has a reading section 7 for installing an IC memory card, and a gas chromatograph main body 1 and an autosampler. 2 and the data processing device 3, the IC memory card 8a is inserted into the reading section 7. One memory card is prepared for each sample (for example, for naphtha analysis, PCB analysis, and fragrance analysis).
b, 8C18d), when the IC memory card 8 corresponding to the sample to be analyzed is inserted into the reading section 7, the data processing device 3 automatically detects the insertion and the built-in program Then, all the analysis conditions stored in the IC memory card 8 are read into the storage means in the data processing device 3, and are stored in the data processing device 3,
All analysis conditions for the chromatograph main unit 1 and autosampler 2 are stored in this IC memory card.
Therefore, after inserting the IC memory card 8 into the reading section 7, the operator changes the RE of the gas chromatograph.
If you start with ADY, the analysis will proceed automatically and you can change the conditions without error.

The analysis conditions stored in the IC memory card 8 include, for example, column temperature, vaporization chamber temperature, detector temperature, detector type, range, polarity, flow rate, and temperature increase conditions. Shown in the figure.

In the above embodiment, the IC memory card 8 is provided for each sample, but for example, the IC memory card 8 is provided for each sample.
A C memory card is prepared as a personal card for each operator, and by storing the operator's own analysis conditions and information in memory, the operator can easily write and keep free information as necessary. be able to.

Furthermore, if you want to use the analysis conditions used elsewhere, you can simply bring that IC memory card and attach it to the gas chromatograph you are processing, and the analysis conditions used previously can be used. It can be used as is, and the analysis conditions can be transmitted by simply copying the analysis conditions used there onto an IC memory card and inserting it into your own gas chromatograph.

Furthermore, for example, if you want to borrow someone else's gas chromatograph for a while, you can store the analysis conditions of that gas chromatograph on an IC memory card, and then you can restore the analysis conditions to the original ones by simply inserting the IC memory card after use. There are also advantages.

Furthermore, although the above embodiments have been described with respect to gas chromatographs, the present invention is not limited to gas chromatographs, and can be widely applied to other chromatographs, such as liquid chromatographs.

(f) Effects of the Invention According to this invention, analysis conditions are set or changed using a memory card. Since there is no need for key operations and input can be made with a single touch, even a novice operator who is not accustomed to handling the system can easily change the settings of the conditions.

Furthermore, even if analysis conditions require frequent changes due to different samples or operators, changes can be made very easily and quickly by replacing one card, greatly expanding the scope of use of the system.
