gas chromatography

a method of chemical analysis used to separate and identify the components of a mixture. The substance being tested is placed at one end of a long tube, and its components are volatilized by an inert gas injected into the tube. Components can be identified by the time they take to pass through the tube. The technique is used to separate and quantify barbiturates, steroids, and fatty acids.
