    Journal: Wei Sheng Yan Jiu; 2006 Jul; 35(4):504-7. PubMed ID: 16986534.
    Abstract:
    OBJECTIVE: To establish a method for determination of volatile organic compounds in drinking water by purge and trap GC/MS. METHODS: Volatile organic compounds in water were purged and trapped by Tekmar 3100, then desorbed and analyzed by GC/MS. Selective ion masses were used in quantitative measurement. RESULTS: 60 VOCs were separated and analyzed in 36 min. Within concentration range from 0 microg/L to 12 microg/L, the correlation coefficient for 51 target compounds was greater than 0.995. The method detection Limits were in the range from 0.021 microg/L to 0.70 microg/L. Recoveries were between 90% and 120%. RF RSD was less than 30%. CONCLUSION: Purge and trap gas chromatography/ mass spectrometry is a sensitive and accurate method for determination of volatile organic compounds in drinking water.
