PPT-Gas chromatography–mass spectrometry (GC-MS) is an analytical method that combines

chromatographyand  mass spectrometry to identify different substances within a test sample Applications of GCMS include drug detection environmental analysis explosives investigation and identification of unknown samples GCMS can also be used in airport security to detect substances in luggage or on human beings Additionally it can identify trace elements in materials that were previously thought to have disintegrated beyond identification.
