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. Aijiren supply GC headspace vial for sale.

Headspace gas chromatography requires headspace vials and caps because they can withstand the pressure from the gas. Chrom Tech has a wide selection of high-quality crimp and screw thread headspace vials available in clear or amber glass with associated 18-and 20-mm headspace closures. Our headspace vials can be ordered as either flat or round

It is important to ensure the correct vial and cap are used! Vial Size: Headspace vials are available in 6, 10 and 20 ml sizes. Use a vial large enough to ensure adequate headspace or phase ratio without excessive dilution of the components of interest. Phase ratio is discussed later and should normally be at least 50 % of the sample volume.
