Centre for Environmental Analysis and Remediation (CEAR) - Gas Chromatography

Gas chromatography combined with a flame ionization detector or with mass spectrometry are analytical instruments particularly useful for chemical characterization, identification and quantification of organic compounds with low molecular weights (< 650amu). CEAR houses a Varian CP-3800 temperature programmable gas chromatograph equipped with two detector systems, a flame ionization (FID) and a mass spectrometer fitted with capillary columns and auto sampler. Mass spectrometric analyses can be performed using both scanning and selected ion monitoring modes.

Some of our applications for GC/MS include:

• Evaluation of the effectiveness of purification procedures
• Characterization of unknown substances
• Identification and quantification of a diverse range of organic compounds
