Gas chromatography/mass spectrometry (GC/MS) is an analytical technique that combines gas chromatography and mass spectrometry to identify unknown substances or contaminants. Due to its precision and accuracy, GC/MS can be used for a variety of applications and industries including biology, food safety, pharmaceuticals, environmental and forensic testing.
Testing Method/Parameter:
Instruction:
The GC-MS instrument allowed for identification and quantification of target compounds in mixtures by mass spectrometer (MS) for molecular mass measurement and gas chromatograph (GC) for separation of mixtures into its components.
