Headspace sampling fundamentals, what is headspace | Aijiren

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 · Dec. 30th, 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.

Headspace Sampling FAQs | Aijiren

What types of samples are typically analyzed using headspace with gas chromatography? Headspace is used to analyze volatile compounds in liquid and solid samples that cannot be injected directly into a gas chromatograph (GC). Examples would be creams and lotions, blood, soil, electronic components, and polymers. Headspace sampling can
