Main function

1. Can automatically run 10 samples without personnel on duty;

2. Startup self-test, fault alarm and prompt, automatic positioning and calibration of sample disk using independent technology;

3 computer program control, the main functions are:

(1) Method parameter setting, real-time animation display working state and running time;

(2) The desorption area, sampling valve, sample transmission tube and secondary desorption area are heated and controlled separately;

(3) Set the analysis program and press the “Run” button to automatically complete all sample analysis;

(4) Normal temperature secondary desorption parts or low temperature secondary desorption parts can be added according to user requirements;

(5) GC and chromatographic data processing workstation can be started synchronously, and the device can also be started by external programs;

4. The machine has the function of standard sample simulation sampling, which can be more convenient to make the working curve through the thermal desorption instrument;

5. The sample tube activation program can be loaded to automatically activate the sample tube after desorption;

6. Through time programming, automatic desorption, purge adsorption, re-desorption, 采样, backblow cleaning and other functions are realized;

7. Electronic refrigeration and second-order thermal desorption processes are used to ensure a narrow chromatographic peak shape;

8. The sample transfer tube and sampling valve have automatic backblowing function to avoid cross contamination of different samples;

9. In order to support the use of imported gas chromatograph more convenient and accurate, the instrument is also equipped with a special interface for various imported instruments, easy connection;

10. For the analysis of active substances, elastic quartz tube can be selected as the sample transfer tube;

11. The needle is easy to change and can be connected to all types of GC injection ports at home and abroad.
