Dynamic Headspace (DHS) is an extraction technique used to concentrate analytes from a solid or liquid sample. The sample is heated and agitated in a sealed vial and the headspace above the sample is purged onto a solid sorbent tube. The solid sorbent tube is then thermally desorbed into the gas chromatograph.
