Headspace Sampling for GC – The Basics. 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

Headspace vials are common for analysis of volatile organic compounds, such as blood alcohol content, pharmaceuticals, and food flavoring analysis. The analytes of interest can be isolated in the gaseous phase, so the gas from the headspace portion of the sample vial is injected onto the GC column. For this reason, a larger vial is required, and our headspace vials offer great sample and autosampler compatibility for various sample types.
