Vapor-Phase Sampling (headspace) for GX
Headspace sampling for determining volatile compounds by GH-PID
Headspace sampling is a sample preparation method for gas chromatography used with GH-PID to determine ethanol and higher alcohols in blood, urine and tissues.
Request a quotationVolatile compounds are transferred from the liquid or solid sample to the gas phase when heated in a closed vial, after which the vapor phase sample is introduced into a gas chromatograph with a flame ionization detector for separation and quantification.
The method is used to determine ethanol and higher alcohols in biological samples - blood, urine and tissues, which is used in toxicological and forensic studies in conjunction with the YL6500 GC gas chromatograph.
Method
- Headspace (headspace) selection of volatile compounds from liquid and solid samples before entering into a gas chromatograph
- Used in conjunction with a flame ionization detector (FID) for the quantification of ethanol and higher alcohols
- Used in toxicological and forensic laboratories for analysis of blood, urine and tissues
