Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. [1]

Headspace gas chromatography connected to an FID and/or an MS detector can be applied to obtain better precision and accuracy for the quantitative analysis of volatile organic compounds (VOCs) in bio-oils including light aldehydes and ketones, ethers, esters, alcohols, carboxylic acids and aromatic compounds [32,49].

is that it can be directly attached the gas chromatograph (GC) inlet via a heated transfer line. After a sample is heated, the gases evolving from the sample get collected in the headspace area between the sample and the vial cap. A needle precisely pierces through the sealed cap and transfers the gas to the transfer line through a heated loop.

Introduction to Headspace and to the Network Headspace Sampler Overview of Headspace Analysis Your new Headspace Sampler is a tool for introducing volatiles and some semi-volatiles that are contained in liquid or solid samples into a gas chromatograph. The analytical technique is called “static headspace gas chromatography.”
