Gas Analysis – Gas Chromatograph

GeoConsult gas composition testing utilizes a micro Gas Chromatograph. Gas Chromatography (or Gas-Liquid Partition Chromatography – GLPC as this process is correctly named) is used to separate and analyse compounds that can be vaporized without decomposition. Relative amounts and purity of compounds can be quickly identified.
