Introduction:
The principle of the AHS-10A automatic headspace sampler is that the sample to be tested is placed in a sealed container, and the volatile components in the sample to be tested are volatilized out of the sample matrix by heating to increase the temperature. In the gas-liquid - solid) two phases to achieve equilibrium, direct extraction of the upper gas chromatographic analysis to detect volatile components in the sample composition and content. At present, the applications and examples of headspace gas chromatographic analysis at home and abroad have the following categories:
⑴ petrochemical: polymer monomer coating, volatile organic compounds;
⑵ environmental science: drinking water volatile halogenated hydrocarbons and industrial waste organic toxic volatile compounds;
⑶ health, epidemic prevention: medical supplies disinfection fumigation residue analysis;
⑷ food industry: wine, vinegar, soy sauce quality control, acetaldehyde residues in packaging materials, leaching oil 6 # solvent residues;
⑸ spices flavor: beer, tea flavor analysis;
⑹ Quality Control of Pharmaceutical Products: Organic Residual Solvents in Pharmaceutical Products;
⑺ Forensic Chemistry: Determination of alcohol, ketone and aldehyde in blood and urine;
