In automated static headspace GC analysis (HS-GC), a sample is thermally equilibrated in a closed headspace vial, and an aliquot of the headspace is introduced 

With single headspace extraction, only one sample of gas is taken from each sample vial. Single headspace extraction is the standard method.

Chapters cover: Principles of static and dynamic headspace analysis, including the HS-GC techniques—vials, cleaning, caps, sample volume, enrichment, ...

For GC to be successful in their analysis, these components need to be volatile, usually with a molecular weight below 1250 Da, and thermally stable so they don

Headspace gas chromatography (Headspace GC) is used to measure volatile compounds that are in the vapor above a solid or liquid sample in a sealed vial.

Suitable for headspace analysis of volatile solids and gases. Store volatile samples to prevent sample evaporation. High-temperature resistance and 

tatic headspace gas chromatography (GC) is a technique used for the concentra- tion and analysis of volume of the sample in the sample vial (Figure 2).

Preconcentration of multiple headspace extracts from the same sample vial if vapours from many litres of air or gas in accordance with standard methods.
