To establish a method for determination of volatile organic compounds in drinking water by purge and trap GC/MS.
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.
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%.
Purge and trap gas chromatography/ mass spectrometry is a sensitive and accurate method for determination of volatile organic compounds in drinking water.
建立吹扫捕集气相色谱/质谱法测定饮用水中挥发性有机化合物的方法。
采用Tekmar 3100对水中挥发性有机化合物进行吹扫捕集，然后解吸并通过气相色谱/质谱进行分析。定量测定采用选择离子质量。
在36分钟内分离并分析了60种挥发性有机化合物。在0μg/L至12μg/L的浓度范围内，51种目标化合物的相关系数大于0.995。方法检出限在0.021μg/L至0.70μg/L之间。回收率在90%至120%之间。相对标准偏差小于30%。
吹扫捕集气相色谱/质谱法是测定饮用水中挥发性有机化合物的一种灵敏、准确的方法。
