What is Gas Chromatography-Mass Spectrometry (GC-MS)?

WebGC and MS – How does it work? Chromatography is the separation of a mixture of compounds into individual components. There are three major steps involved with separating and identifying components of a mixture using a GC. They are: Injecting a sample into the GC. (This takes place at the inlet.) WebGC-MS is the best way for forensic experts to identify substances because it is a specific test. A specific test positively identifies the actual presence of a particular substance in a given sample. A non-specific test only says that categories of substances are in the sample. foa shock partsWebFeb 28, 2024 · In this article.
