2、 InstrumentCharacteristics and main functions
1. It can automatically run two channels, one each-30 samples, no need for personnel on duty;
2. Power on self-test, fault alarm and prompt, automatic positioning and calibration of sample disk;
3. Microcomputer program control, with main functions including:
⑴ Method parameter setting, real-time animation display of working status, and running time;
⑵ The desorption zone, injection valve, sample transfer tube, and secondary desorption zone are all separately heated and temperature controlled;
⑶ Can start synchronouslyGC、 The chromatographic data processing workstation can also be started with external programs;
4. The machine comes with the function of simulating and sampling standard samples, which makes it more convenient to create working curves through a thermal desorption instrument;
5. The built-in sampling tube activation program can be loaded to automatically activate the desorbed sampling tube;
6. Through time programming, automatic functions such as desorption, blow adsorption, re desorption, injection, and backwash cleaning can be achieved;
7. The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;
8. In order to make it more convenient to use in conjunction with imported gas chromatographsaccurateIndeed, this instrument is also equipped with dedicated interfaces for various imported instruments, making it easy to connect;
9. For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube;
10. The injection needle is easy to replace and can be connected to all models at home and abroadGC injection port.
