网页Introduction. Headspace analysis is a technique for sampling and examining the volatiles associated with a solid or liquid sample. The actual headspace itself is the volume of vapor or gas above the sample. For most headspace analysis purposes the sample and its associated headspace are held within an enclosed container (Figure 1 ).
