Product Description

1, Purpose and scope of application

Headspace injection device is a sample pre-treatment device for gas chromatography analysis. Compared with other sample pre-treatment methods such as solvent extraction and thermal desorption, it is simpler and more practical, with higher work efficiency and better reproducibility of chromatographic analysis results. It is one of the preferred methods for trace analysis in gas chromatography and is widely used:

(1) Petrochemical industry: analysis of volatile organic compounds in high polymer monomer coatings, etc;

(2) Environmental Science: Analysis of volatile halogenated hydrocarbons in drinking water and organic toxic volatile compounds in industrial wastewater;

(3)Hygiene and epidemic prevention: Analysis of disinfection and fumigation residues in medical supplies;

(4) Food industry: quality control of colored wine, vinegar, and soy sauce; Residual amounts of acetaldehyde and other substances in packaging materials; Analysis of residual 6 # solvent in extracted oil, etc;

(5) Flavor essence: flavor analysis in beer and tea;

Quality inspection of drugs: analysis of organic residual solvents in drugs;

Forensic chemistry: determination of ethanol, ketones, and aldehydes in blood and urine;

Other: such as the determination of volatile organic compounds in soil.
2, Working principle

The principle of the AHS-6890 automatic headspace injection device is to place the test sample in a closed container, heat and raise the temperature to evaporate the volatile components in the sample matrix, and reach equilibrium in the gas-liquid (or gas-solid) phase. The upper gas is directly extracted for chromatographic analysis, thereby detecting the composition and content of volatile components in the sample.
