US EPA Method 524.4 using the Teledyne Tekmar Atomx XYZ and Thermo Scientific ISQ 7000 Mass Spectrometry (MS) System Coupled with a Thermo Scientific TRACE 1310 Gas Chromatograph (GC)
Abstract US EPA Method 524.4 was used to determine the concentration of volatile organic compounds (VOCs) in drinking water. The Teledyne Tekmar Atomx XYZ purge and trap (P&T) VOC sample preparation system combined with a Thermo Scientific ISQ 7000 Mass Spectrometry (MS) system coupled with a Thermo Scientific TRACE 1310 Gas Chromatograph (GC) was used to create a working linear (r²) ...

US EPA Method 524.2 using the Teledyne Tekmar Atomx XYZ and Thermo Scientific ISQ 7000 Mass Spectrometry (MS) System Coupled with a Thermo Scientific TRACE 1310 Gas Chromatograph (GC)
Abstract US EPA Method 524.2 was used to determine the concentration of volatile organic compounds (VOCs) in drinking water. This method is effective at concentrating trace levels of VOCs, however it can also transfer a significant amount of water vapor to the Gas Chromatograph/Mass Spectrometer (GC/MS) due to the four-minute desorb time recommendation. The Teledyne Tekmar Atomx XYZ purge and ...

Shimadzu Guide to US EPA Method 8260 for analysis of volatile organic compounds in groundwater and solid waste
Environmental contamination has been at the forefront of government policy and regulation since the US EPA was established in 1970. Over the years the US EPA has developed, published, and updated multiple methods for analysis of environmental pollutants, and single-quadrupole gas chromatography-mass spectrometry (GC/MS) has long been the technique of choice for determination of volatile organic ...

Validation of New VPH GC/MS Method using Multi-Matrix Purge and Trap Sample Prep System
Abstract The Massachusetts Department of Environmental Protection (MassDEP) developed the “Method for the Determination of Volatile Petroleum Hydrocarbons (VPH) by Gas Chromatography/ Mass Spectrometry” to measure the collective concentrations of volatile aliphatic and aromatic petroleum hydrocarbons in aqueous and soil/sediment matrices1. The previous method for VPH determination ...

U.S. EPA volatile organics method 524.2 using PURGE and TRAP GC/MS
Clean drinking water is of worldwide interest. Contaminants can compromise the quality of a water supply and cause short- and long-term health effects. Stringent water quality criteria help to ensure safe drinking water by requiring the detection and quantification of a wide variety of contaminants at extremely low levels. U.S. EPA Method 524.2 (1) provides the guidance necessary for identifying ...

Validation of Wisconsin Gasoline Range Organics
Abstract The Wisconsin 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 ...
