Automatic process gas chromatography is used in the industry for identification and quantification of chemical compounds in both their gas and liquid phases. Gas chromatograph instruments vaporize and distribute samples between a stationary and mobile phase, whereby a chemically inert gas carries molecules through a heated column. After column separation, molecules can be identified and quantified precisely. Ideally, industrial systems are equipped with their own gas generators (cylinder-free) so that they are completely autonomous.
