Headspace GC/MS Analysis. Headspace gas chromatography/ mass spectroscopy is the analysis of the volatile and semi-volatile organic compounds given off by a sample during heating or over time. 0.1-10 grams is the typical sample size, and virtually any sample that’s not highly volatile can be tested.

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.

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).

18mm Headspace Vials & Closures. Unlike crimp cap vials, Thermo Scientific™ National 18mm Screw Top Headspace Vials require no tools for closure. Manufactured with superior quality (Type 1, Class A) glass, they are available with a round bottom in sizes with usable volumes of 10mL or 20mL. The 18mm vials feature Magnetic Screw Caps which

Static headspace GC (SH-GC) is a commonly used technique in the analysis of these OVIs. This technique concentrates volatile analytes, and allows for their analysis free from sample matrix.
