2、 InstrumentCharacteristics and main functions

1. It can automatically run 1-20 samples without the 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 Set up the analysis program and press the run button to automatically complete the analysis of all samples;

⑷ The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started by 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. Through time programming, automatic functions such as desorption, blow adsorption, re desorption, injection, and backwash cleaning can be achieved;

6. Adopting electronic refrigeration and second-order thermal desorption process to ensure narrow chromatographic peak shapes;

7. The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;

In order to provide more convenient and accurate use for imported GC and GCMS, this instrument is also equipped with dedicated interfaces for various imported instruments,Can connect all models both domestically and internationallyGC、GCMS；

9. For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube;
