Description

HS-126 fully automatic headspace injection is used to achieve fully automated processes such as sample heating balance, injection, automatic start of chromatographic analysis, cleaning, etc., ensuring chromatographic analysis accuracy and improving chromatographic analysis efficiency!

Characteristics and main functions of the instrument

1. Can automatically run 1-126 samples without the need for personnel on duty;

2. Power on self-test, fault alarm and prompt, automatic positioning of sample disk;

3. Automatic leak detection to ensure that there are no leaks in the injection pipeline and sample bottle;

4. Using a robotic arm to grab the headspace bottle quickly and accurately;

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

6. Set up the analysis program, press the run button to automatically complete all sample analysis, and the sample dynamics can be displayed in real-time on the screen; 7. Through time programming, automatic functions such as pressurization, sampling, injection, analysis, and post analysis blowback cleaning can be achieved;

8. All sample flow paths have undergone insulation treatment and chemical inerting treatment. After each injection is completed, the system automatically uses inert gas to blow the sampling pipeline and quantitative ring to prevent cross contamination.

9. Can achieve multiple injections of the same sample for analysis, used for method expansion and research;

10. Automatic oscillation function, the headspace bottle oscillates vertically in a wavy shape during the heating position balance rotation process, shortening the balance time and improving the balance efficiency;

11. 7-inch touch screen display, easy to operate, can store multiple national standard methods;

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

13. Adjust the pressure valve to display real-time pressure values of the pressurized gas and carrier gas

14. The injection needle is easy to replace and can be connected to all models of GC injection ports at home and abroad.
