Gas Chromatography (GC-FID/TCD/FPD Analysis) Testing Technique
Gas Chromatography (GC) 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.
Flame-ionisation detectors (FID), Flame photometric detectors (FPD) and thermal conductivity detectors (TCD) are useful for determining the concentration of specific compounds.
- Rapid, quantitative, cost effective and compound specific
- Can be performed with minimal sample preparation or clean up
- Quantification of bulk gases methane, carbon dioxide, carbon monoxide, N2, O2, Ethane, Propane, Acetylene, Ethylene and helium
- Quantification of hydrogen sulphide, mercaptans, DMS and carbon disulphide
- Characterization and quantification of oils and fuels and phthalates.
Typical Applications
- Quantification of bulk gases in landfill gas and biogas
- Quantification of sulphurous compounds in landfill gas and biogas
- Determination of carbon monoxide for landfill underground fires
- Determination of TPH content of wastes
- Determination of phthalate content in children’s toys and packaging for medical devices.
Typical Industries using Gas Chromatography
- Medical devices
- Automotive
- Materials
- Waste water treatment plants
- Landfill operators
- Waste treatment plants
- Manufacturers of children's toys.
