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 vials and caps are used in headspace gas chromatography analysis because of their ability to withstand the pressure from gas. Aijiren headspace vials come in two basic sizes (10 mL headspace vials and 20 mL headspace vials). Both flat bottom and round bottom styles are available for use in a wide variety of headspace instrument platforms.
