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).

Headspace is used to analyze volatile compounds in liquid and solid samples that cannot be injected directly into a gas chromatograph (GC). Examples would be creams and lotions, blood, soil, electronic components, and polymers. Headspace sampling can accommodate virtually any matrix. How does headspace sampling work?

Thermo Scientific 20mm crimp top and 18mm screw top headspace vials are available in clear or amber glass in sizes ranging from 6mL to 27mL. Choose from a round or flat base with a beveled or square edge finish. Round base vials are compatible with most autosamplers and more easily handled by robotic arms that lift the vial from the tray.
