Gas chromatography–mass spectrometry (GC-MS) is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. Analysis begins with the gas chromatograph, where the sample is effectively vaporized into the gas phase and separated into its various components using a capillary column coated with a stationary phase. Once the components leave the GC column, they are ionized and fragmented by the mass spectrometer using electron ionization sources. Ionized molecules and fragments are then accelerated through the instrument’s mass analyzer. It is here that ions are separated based on their different mass-to-charge (m/z) ratios. The core facility hosts three Agilent single quadrupole GC-MS.

GC-MS is highly effective and versatile analytical techniques with numerous scientific applications to cater the field of applied Sciences and Technology.
