Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.

Gas chromatography mass spectrometry (GC/MS) has long been used in industry to identify and quantify unknown components in compounds down to ultra-trace levels. GCMS is ideal for impurity analysis and as a QC method. GCMS provides trace-level molecular characterization of many sample types and is a powerful analytical tool for trace and ultra

Jun 01, 2021 · We applied headspace gas chromatography using a dual column/dual flame ionization detector (HS-GC-FID/FID), a technique routinely used in forensic toxicology. The method was linear in range, from 0.01 to 20.0%, with a coefficient of determination of 0.999 (R2).

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.

Jan 01, 2021 · The term “headspace” in gas chromatography (GC) denotes the vapor phase within a sealed container also containing a liquid or solid. Usually, the vapor is above the liquid or solid, at the top of the container, hence the term “headspace.”. Headspace extraction refers to the collection and analysis of the vapor phase in the container.

Get aHEAD of your volatiles problem with HEADSPACE. In the world of volatiles analysis, Headspace Gas Chromatography Mass Spectrometry (HGCMS) supersedes its competitors through the direct injection of volatiles. Highly volatile and low boiling compounds are preferentially evolved from a sample into the headspace gas during gentle heating.

3.9.3 Headspace gas chromatography. 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
