Headspace Sampling for GC – The Basics. Headspace sampling is a type of sample introduction technique for gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). For headspace techniques, the gas layer, or the headspace above the sample in a vial, is analyzed as opposed to withdrawing a volume from within the sample layer (Figure 1).

Dec 30, 2019 · Headspace GC is a sampling technique that involves the indirect determination of volatile components in liquid or solid samples by analyzing the gas phase in which the sample in the closed system is in a thermodynamic equilibrium. It is mainly used to determine volatile components in trace amounts.

Nov 29, 2018 · Headspace GC is used for the analysis of volatile and semi-volatile organics in solid, liquid and gas samples. The popularity of this technique has grown over recent years and has now gained worldwide acceptance for analyses of alcohols in blood and residual solvents in pharmaceutical products.
Headspace GC is a sampling technique that involves the indirect determination of volatile constituents in liquid or solid samples by analysing the vapour phase that is in thermodynamic equilibrium with the sample in a closed system [ 149, 150 ]. It is used predominantly for the determination of volatile constituents present in trace concentrations.
