Gas Chromatography Gas Chromatography - GC is a common technique used to separate and identify volatile organic compounds (analytes). As the gas moves the analyte across the stationary phase, the analyte will be in equilibrium with the gas and the liquid phase (usually suspended on a solid surface). - The mobile phase is an inert gas. Commonly used gases include N 2 , He, Ar, and CO 2 , depended on the type of detector. -T h e stationary phase is a high-boiling liquid film supported on an inert solid and packed in either a fused silica (12 to 30 meter) capillary column or in a copper or stainless steel (1.5 to 3.0 meter) metal column. - This method depends upon the solubility and the boiling point of the volatile organic liquid in order to separate them from a mixture. - It’s both a qualitative (identity) and quantitative
