GC-MS

About the technique:

Gas Chromatography-Mass Spectrometry (GC-MS) is a method of separating mixtures of volatile compounds in the gas phase using a temperature gradient. This instrument includes a headspace sampler, which can be used to inject gaseous samples directly onto the column.

This instrument has two detectors (in parallel);

1. A Flame Ionisation Detector (FID) uses pyrolysis to detect carbon-containing compounds that are present in the carrier gas flow.  
2. A mass spectrometer (MS) measures the mass-to-charge ratio of the ionised compounds.
