Features and application:
Gas chromatography-mass spectrometry (GC-MS) is an instrument that combines gas chromatograph and mass spectrometer. The effective combination of mass spectrometry and chromatography is used for qualitative and quantitative analysis of low boiling point and heat stable organic matter. It can realize multi-component simultaneous analysis with ultra-high sensitivity in food safety, environment, forensic medicine, clinical and many other fields.
