Gas Chromatography (GC)
Gas Chromatography (GC) is a widely used analytical technique for separating and analyzing compounds that can be vaporized without decomposing. In GC, a sample is injected into a stream of inert carrier gas, which transports it through a column coated with a stationary phase. As the mixture travels through the column, different compounds separate based on their volatility and interaction with the stationary phase. A detector then records their presence as distinct peaks, providing both qualitative and quantitative information. GC is commonly applied in environmental testing, pharmaceuticals, petrochemicals, food and beverage analysis, and forensic science. It is particularly effective for detecting volatile organic compounds, gases, and small molecules with high sensitivity and precision.
