Agilent 6890/5975 GC/MS System
Agilent 7890 GC System
Gas Chromatography Mass Spectrometry (GC/MS) and Gas Chromatography (GC) are techniques for the analysis and quantitation of volatile and semi-volatile organic compounds in water, wastewater, sludge, or soil samples. GC/MS is a powerful analytical technique that combines two techniques into a single analysis to allow both qualitative and quantitative separation and environmental contaminants identification. We rely on both the NIST library and our own internal library for the GC/MS identification of the contaminant compounds. Truesdail uses gas chromatography with either a flame ionization detection (FID) or an electron capture detector (ECD).
For the analysis of volatile and semivolatile organic compounds such as those listed in the US EPA Methods 552, 524, 625, 624, 608, 8015, 8270, and 8260 Truesdail uses both GC/MS and GC techniques. For the determination of volatile organic compounds (VOCs) including BTEX, Truesdail utilizes purge and trap/gas chromatography mass spectrometry (P&T/GC/MS). The gas chromatography technique is very sensitive technique to quantitate either halogen containing target compounds (PAHs) or petroleum compounds found in diesel and gasoline.
