2、 InstrumentCharacteristics and main functions

1. Power on self-test, fault alarm and prompt;

2. Color touch screen display, controlled by microcomputer program, with main functions including:

⑴ Method parameter setting, real-time 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 entire sample analysis;

⑷Normal temperature secondary desorption components or low-temperature secondary desorption components can be added according to user needs；

⑸ The GC and chromatographic data processing workstations can be started synchronously, and the device can also be started using external programs;

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

4. Through time programming, automatic functions such as desorption, blow adsorption, re desorption, injection, and backwash cleaning can be achieved;

5. 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;

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

7. In order to make it more convenient and accurate to use with imported gas chromatographs, this instrument is also equipped with dedicated interfaces for various imported instruments, which are easy to connect;

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

9. The injection needle is easy to replace and can be connected to all models at home and abroadGC injection port.
