Gas Chromatography (GC) is a widely used analytical technique that separates and analyzes compounds within a mixture. It operates on the principle of compound distribution between a stationary and mobile phase within a column. As compounds travel through the column, they interact differently with the stationary phase, leading to their separation based on molecular properties. GC is valued for its ability to analyze complex mixtures with high resolution, speed, and sensitivity, making it essential in diverse fields such as environmental monitoring, pharmaceuticals, food and beverage testing, and forensic science.
