Gas chromatography (GC) is an analytical technique used to separate and analyze compounds that can be vaporized without decomposition. It is widely used in various fields, including environmental studies, pharmaceuticals, and food safety. The method involves volatilizing the sample and transporting it through a column with an inert gas, usually helium or nitrogen. Each compound in the sample interacts differently with the column material, causing them to elute at different times, known as retention times.
