Fully automatic headspace gas chromatographIt is an analytical instrument based on headspace sampling technology combined with gas chromatography, which achieves qualitative and quantitative analysis by measuring the distribution of organic volatile components in the vapor phase at the top of the sample. It has the characteristics of high sensitivity, rapid temperature rise, and fully automatic operation, and is widely used in environmental detection, food safety, forensic chemistry, petrochemical and other fields.

Fully automatic headspace gas chromatographComposition:

Headspace sampler: It is a key component that can automatically complete the steps of sample bottle loading, heating balance, gas extraction, injection, etc. It has high-precision temperature control function. The sample bottle heating zone, transmission pipeline, and injection valve are usually independently controlled by three channels. It also has pressure balance injection technology, anti cross contamination design, etc.

Gas chromatograph: including gas path system, injection system, chromatographic column, detector, etc. The pneumatic system provides a stable carrier gas; The injection system introduces headspace gas into the chromatographic column; Chromatographic columns are used to separate various components in samples; The detector detects the separated components, and common detectors include hydrogen flame ionization detector (FID), electron capture detector (ECD), etc.
