Open publisher page 0 citations

Abstract

A analytic method of purge and trap concentration with gas chromatography and mass spectrometry (GC/MS) was established for determination of 13 kinds of volatile organic compounds (VOCs) in drinking water.The recovery ratios of the method were 90%～110%,and relative standard deviations (n=7)were generally lower than 5.0 % for 30 μ g/L standard VOCs.This method is sensitive and accurate.The application of the method to the determination of VOCs in real sample of drinking water was tested and the satisfactory results were obtained.
