Organic Geochemistry Laboratories

The Organic Geochemistry Facility (led by Dr Jessica Whiteside) hosts a variety of instruments designed to characterise organic matter from the environment and the geological record. The facility has dedicated sample preparation lab, wet chemistry lab space, and an instrumentation lab utilizing state-of-the-art gas chromatographs (GC) linked to various mass spectrometers, including a GC-isotope ratio mass spectrometer. For further information, please contact Dr Jessica WhitesideDr Gordon Inglis or Dr Sargent Bray.

Equipment

Our facility specialises in the extraction, purification, separation, and chemical and isotopic characterization of complex organic mixtures found in biological and environmental materials. Gas chromatography (GC) is used to separate complex mixtures of volatile compounds. A range of hyphenated techniques (e.g. GC-mass spectrometry) are then used to characterise these complex mixtures. We also operate a GC-isotope ratio mass spectrometer (GC-C-IRMS) which enables compound specific δ13C, δ15N and δ2H value determinations.
