Gas Chromatography-Mass Spectrometry (GC-MS Analysis)
Gas Chromatography-Mass Spectrometry provides a quantitative analysis of volatile and semi-volatile organic compounds found in a variety of matrices (gases, liquids and solids) in foods, medical materials, plastics, environmental samples and occupational monitoring samples.
Mass spectrometers are useful for determining the concentration of known compounds and providing identifications of unknown compounds.
- Analysis is sensitive and specific
- Can quantify 2 or more co-eluting peaks of different chemical structures
- Can provide qualitative data as well as quantitative data
- Good starting position for the identification of unknown compounds, odours or initial tests of unknown material contaminants
- Can be used for a much wider range of compounds types than an FID, TCD or FPD as long as the compound can be volatilised below 340°C.
- Quantification of Trace Volatile organic gases in landfill gas and biogas
- Residual solvent analysis in pharmaceuticals and medical materials
- Identification of some unknown odour sources
- Identification of unknown contaminants
- Identification and quantification of siloxanes in landfill gas and biogas.
Typical Industries using Gas Chromatography
- Medical devices and materials
- Waste water treatment plants
- Landfill operators
- Waste treatment plants
- Manufacturers of children's toys.
