Headspace Gas Chromatography an overview | ScienceDirect

Headspace GC–MS is the most commonly used technique for volatile organic extractables. Some representative starting conditions are given in Table 13.5 . Analyzing the sample neat directly from the headspace vial following an oven incubation as part of the instrument method will usually yield a higher level of extractables than analyzing
