GC/MS Analysis of Volatile Organic Compounds in Drinking Water: Productivity Solution for US EPA Method 524.2
11 Feb 2015The GC/MS analysis of volatile organics in drinking water according to United States Environmental Protection
Agency (US EPA) Method 524.2 offers a number of analytical challenges, ranging from water handling to very low target compound concentrations. It requires a highly sensitive mass spectrometer in order to achieve the required method detection limits. This application note demonstrates that the Thermo Scientific DSQ™ II GC/MS system provides excellent sensitivity and allows for the use of a 5 mL purge.

GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.
