Gas Chromatography and GC-MS.

Gas chromatography separates, and with mass spectrometry, identifies the volatile and semi-volatile components of mixtures.  Samples can be in the form of gases liquids or solids.  Special techniques are available to extract volatiles from solids or solutions and field sampling is also available.  Sensitivities from ppb to % levels.
