Validation of Wisconsin Gasoline Range Organics

The Wisconsin Department of Natural Resources (DNR) Modified Gasoline Range Organics (Wisconsin GRO) Method is used to determine gasoline and gasoline components in water and soil. The water samples are analyzed by purge and trap, while the soil samples undergo an additional methanol extraction. For this application note, a working linear calibration curve and quality control checks were evaluted by using a Teledyne Tekmar’s Atomx Automated VOC Sample Prep System. The Atomx utilizes an automated methanol extraction and purge and trap concentrator in conjunction with a gas chromatograph mass spectrometer (GC/MS) to determine the concentration of gasoline and gasoline components in water and soil samples.
