If the analytes are very volatile, they can be sampled, injected and then separated as gases. One of the techniques for this is headspace GC
Feb 29, 2012 Although it is possible — and sometimes even desirable — to sample and inject headspace directly into a GC system with a hand-held syringe, most ...

tatic headspace gas chromatography (GC) is a technique used for the concentra- Most of the autosampling units can retrofit to a standard GC with.
The characteristics of the GC/MS method made available to us (US FDA, GC-MS chromatograms of a headspace of 2 ng/g furan standard (d4-furan-250 ng/g).
The technique of reverse headspace analysis has been applied to such samples. The gas, the minor impurities of which are to be determined, is equilibrated with
(4) For separation of analytes in the gas phase, trapping analytes from vapor samples and headspace analysis are used. As a result, sample preparation is not
