2、 InstrumentCharacteristics and main functions
1. It can run automatically-10 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 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. 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. Adopting electronic refrigeration and second-order thermal desorption process to ensure narrow chromatographic peak shapes;
8. The sample transfer tube and injection valve have automatic blowback function, which avoids cross contamination of different samples;
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.
