Sep 10, 2002 · The classical technique and the simplest way to try headspace analysis for the first time is to seal the sample in a gas-tight vial, using a closure with a septum and to use a gas-tight syringe to sample the vapors within the vial. This is called static headspace sampling and numerous instruments are available for its automated application.

3.9.3 Headspace gas chromatography Headspace GC is a sampling technique that involves the indirect determination of volatile constituents in liquid or solid samples by analysing the vapour phase that is in thermodynamic equilibrium with the sample in a closed system [ 149, 150 ].
of ethanol and other volatiles in blood is gas – liquid partition chromatography with headspace (HS) sampling technique and this technology has been available since the 1970s (Jones, 2013). 6.1
May 28, 1999 · Gas chromatography has proven to be a very useful analytical technique for in situ analysis of extraterrestrial environments as demonstrated by its successful operation on spacecraft missions to Mars and Venus. The technique is also one of the six scientific instruments aboard the Huygens probe to explore Titan's atmosphere and surface.
