Main performance characteristics:

1. Up to the number of working positions for headspace bottles20It is a metal body heating with high temperature control accuracy and small gradient;

2. Touch color screen, automatically realize functions such as pressurization, sampling, injection, analysis, and post analysis blowback cleaning through time programming;

3.Not only is there a display of various time process statuses on the screen, but there are also flashing light prompts for various job statuses, greatly facilitating user operation and use;

4.Equipped with an external carrier gas regulation system, there is no need forGCAny modifications or changes to the instrument can be made for headspace sampling analysis, or the original instrument carrier gas can be used to make installation simple;

5. The use of pressure equilibrium injection technique for headspace injection can obtain narrow chromatographic peak shapes;

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

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

8. The injection volume can be adjusted at any time according to the concentration of the sample to be analyzed by the customer;

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

10.Curved structure, beautiful, generous, and practical;

11. Microcomputer program control, main functions include:

⑴ Method parameter setting, real-time working status, three-way temperature control, and each running time;

⑵ The sample area, injection valve system, and sample transfer tube are all individually heated and temperature controlled;

⑶ Set the control program and press the start button to automatically complete the entire sample analysis;

⑷ Storable9speciesMethod, easy to call at any time, achieves fast startup and analysis;

⑸ Can start synchronouslyGCThe chromatographic data processing workstation can also be started with external programs.
