| Abstract: | A method is established for determination of 27 volatile organic compounds in water by purge and trap-gas chromatography/mass spectrometry.Full scan mode,selective ion mode and the internal standard method are used to improve the accuracy of the qualitative and quantitative analysis.The detection limit is in a range of 0.04μg/L~2.8μg/L,the recoveries are between 82.7%~108% and the RSD lies between 1.42%~8.68%. |
