Poster Information
Abstract: Volatile contaminants in drinking, ground and waste waters are an ongoing environmental concern throughout the world. Testing for these contaminants is generally done using a Gas Chromatograph (GC) coupled to a Mass Spectrometer. However, sampling for these compounds is dependent on the environmental regulations of the country in which you are testing. The USEPA methods for extracting VOCs from environmental samples require purge and trap sampling. On the other hand, in Europe and Canada, it is common to use static headspace sampling for the measurement of VOCs. Summary: Static headspace sampling has always been a viable option for the detection of Volatile Organic Compounds (VOCs) and is readily used in Europe and Canada for testing water samples. In order to detect low level contamination of water, it is essential for the static headspace sampling and GCMS analysis parameters to be enhanced. The linearity, detection limits and precision and accuracy of static headspace sampling will be compared with USEPA Method 8260 requirements.References: 1.
