Description
Headspace gas chromatography–mass spectrometry
2009/1/1 · Static headspace (SHS)–GC is a technique suitable for determining volatile compounds in food samples. The operation of the SHS implies that the solid sample was placed in a sealed vial, heated (thermostating temperature) in an oven during a time period (thermostating time) and the volatile compounds in the solid phase are allowed to reach the equilibrium with the gas phase.

Headspace Vials might differ in: Volume (5ml, 10ml, 20ml) Rounded or flat bottom. A rounded bottom is more sturdy and thus more resistant to the high pressure within the vial during the heating process. Furthermore the vial slides more easily into the heating block when being transported by a magnet.
