Semivolatile organic compounds in drinking water by solid-phase extraction and capillary column (GC/MS)
4 Aug 2025This application note details EPA Method 525.3 for the determination of semivolatile organic compounds in drinking water. Using UCT's ENVIRO-CLEAN® 525 C18 SPE cartridges, the method combines solid-phase extraction (SPE) and gas chromatography/mass spectrometry (GC/MS) to deliver accurate and reliable quantification of pesticides, herbicides, and other organic pollutants in water samples.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Drinking Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).GC-MSGas Chromatography-Mass Spectrometry (GC-MS) combines the separation power of gas chromatography with the detection capabilities of mass spectrometry, allowing for the analysis of complex mixtures. It is widely used in environmental, forensic, and pharmaceutical analysis.
