Fully automatic headspace sampler HS-20

Fully automatic headspace sampler HS-20It is a 20 bit upgraded fully automatic headspace sampling device using valve and quantitative ring injection technology. The instrument realizes fully automatic sample operation, with the characteristics of fast running speed and easy operation.Allow free addition of samples during the experimental process, and for emergency samples, they can be added at any time and analyzed first. Adding samples at any time and prioritizing analysis can meet users' needs for early testing of emergency samples.

Fully automatic headspace sampler HS-20Instrument features:

1. 7-inch touch screen, comprehensive and intuitive, can real-time grasp the operation of the instrument and the current status of each sample;

2. Realize fully automatic operation, capable of automatically running 1-20 samples, continuous analysis, unmanned operation, set up analysis program, complete all sample analysis;

3. Automatically locate and calibrate the sample tray to prevent bottle jamming caused by misalignment;

4. The starting and ending bottle positions can be freely set to meet special on-site requirements;

5Allow free addition of samples during the experimental processNo need to interrupt the running experimental sequence;

6For the analysis of emergency samplesCan be added urgently and analyzed first;

7. Through time programming, automatic functions such as pressurization, sampling, injection, analysis, and post analysis blowback cleaning can be achieved;

8. Can synchronously start GC and chromatographic data processing workstations;

9. 3-channel events, programmable automatic operation, can store 100 methods, can be called at any time, achieving fast startup and analysis;

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

11. Power on self-test, fault alarm and prompt, temperature overload protection function, increase the safety factor of instrument use;

12. The sample transmission pipeline and injection needle are made of inert materials to prevent sample residue and loss;

13、The peak shape of headspace injection is narrow and the repeatability is good,Using valve and quantitative ring injection technology, fixed volume and known volume samples, accurate temperature control ensures good reproducibility;

14. All sample flow paths have undergone insulation treatment and inert treatment, which greatly reduces analysis residues and maintains the integrity of the sample;

15. After each injection is completed, the system automatically uses inert gas to blow the sampling pipeline and quantitative ring to prevent cross contamination;

16. The instrument is equipped with interfaces for various domestic or imported instruments, which can be connected to GC and GCMS at home and abroad, with strong universality;

17、Install dust cover on sample trayPrevent dust, impurities, and other contaminants from contaminating the sample, thereby ensuring the purity of the sample and the accuracy of the experimental results.
