GC (Gas Chromatography)

Gas Chromatography (GC) is an analytical technique used to separate and identify different compounds within a mixture. It works by vaporizing the sample and passing it through a long, heated tube filled with a special material called a stationary phase. As the mixture moves through, components separate based on their interactions with the stationary phase and their volatility. More volatile or less interacting substances travel faster and exit the column sooner. A detector then records each component as it elutes, creating a chromatogram that helps identify and quantify the substances present.
