Title: Determination of Volatile Organic Compounds in Groundwater Samples by Purge and Trap-Gas Chromatography-Mass Spectrometry
Abstract: A method for the determination of 25 volatile organic compounds,including halohydrocarbons,benzene series,chlorobenzene and etc.,by purge and trap-GC/MS in groundwater samples from China Groundwater Survey Project was developed.The detection limits of the method for VOCs were in the range of 0.1~0.4 μg/L and the recoveries were between 88.8%~112.0% with precision of 1.73%~5.53%(n=7).The correlation coefficients of the calibration curve equations for the analytes were better than 0.9995.A quality control procedure for semi-volatile organic compound analysis in groundwater was also proposed.The method provides the advantages of high sensitivity,high accuracy and precision,simple operation and is suitable for batch analysis.
