Gas Chromatography For Accurate Analysis

Gas Chromatography (GC) is an analytical technique used to separate, identify, and quantify volatile compounds in a mixture. The sample is vaporized and carried by an inert gas (mobile phase) through a column containing a stationary phase, where components are separated based on their volatility and interaction with the column material. GC is widely used in environmental analysis, pharmaceuticals, food and beverage testing, petrochemicals, and forensic science for applications such as purity testing, quality control, and trace-level compound detection. Modern GC systems may include detectors like FID, TCD, or MS for enhanced sensitivity and specificity.
