Gas Chromatography–Mass Spectrometry (GC-MS) is an analytical technique that combines gas chromatography and mass spectrometry to separate, identify, and quantify volatile and semi-volatile organic compounds.

GC-MS allows injection of liquid or gas samples. In the gas chromatography stage, volatile organic compounds are separated, while in the mass spectrometry stage, chemicals are detected as gas-phase ions by measuring their mass-to-charge ratio.

GC-MS is a powerful technique used for various applications, including the detection of trace organic compounds such as pharmaceuticals, pesticides, polycyclic aromatic hydrocarbons, and disinfection byproducts. Additionally, it can identify unknown environmental intermediates.
