GCMS (Gas Chromatography-Mass Spectrometry)

GC-MS (Gas Chromatography-Mass Spectrometry) is a powerful analytical technique used to identify and quantify chemicals in a sample. In the first part, gas chromatography separates different substances in a mixture by heating them, causing them to vaporize and travel through a column. Each substance moves at a different speed, allowing for separation. The second part, mass spectrometry, then identifies these substances by measuring their mass and charge. Together, GC-MS provides detailed information about the chemical composition of samples, making it essential in fields like environmental testing, pharmaceuticals, and forensic analysis.
