Gas Chromatography Mass Spectrometry

About GC-MS

Gas chromatography mass spectrometry (GC-MS) is an analytical method for identifying and quantifying volatile compounds in a complex mixture (gas or liquid). The instrument is composed of two main components: a gas chromatograph and a mass spectrometer. As the temperature ramps up over time in the gas chromatograph, components in the complex mixture are separated and travel through the capillary column allowing the mass spectrometer to ionize and detect individual components. GC-MS is often used in forensics, drug detection, pharmaceutical research, environmental sample analysis, food science, and much more!
