An Alternative Method to RSK 175 using a Purge and Trap Concentrator and GC/FID

With the growing price of oil, many alternative energy sources are being explored. Natural gas prices are actually decreasing, in large part to the use of hydraulic fracturing in areas like the Marcellus Shale in Pennsylvania. Due to increased concern over the hydrofracturing process and the release of methane and other chemicals into the local drinking water, a need has developed for fast and accurate analysis of methane in water. This study will evaluate a method developed for the determination of methane, ethane, ethene, and propane in water using a Purge and Trap concentrator, autosampler, and GC/FID. Comparisons to current headspace methods, RSK 1751 and BOL60192, will be made.
