摘　　要：使用水质有机污染物GC/MS分析专家系统,按照吹扫捕集/气相色谱-质谱法快速检测地表水中的5 5种挥发性有机物。结果表明,＂水质有机污染物GC/MS分析专家系统＂快速的实现了55种挥发性有机物的定性定量,其校正曲线相关系数在0.9904-0.9 999之间,样品加标回收率在78.1 9%-128.46%之间,方法检出限在0.03μg/L-1.20μg/L之间,相对标准偏差为2.15%-11.38%。专家系统在水中挥发性有机物检测中具有快速、智能、专用的优势。The GC/MS-Expert-Water System was used to detect 55 kinds of volatile organic compounds in surface water, according to the method of purge and trap/gas chromatography-mass spectrometry.The results showed that the GC/MS-Expert-Water Systems quickly realized the qualitative and quantitative analysis of 55 kinds of volatile organic compounds. The correlation coefficients of the calibration curve were between 0.9904-0.9999,and the recoveries were in the range of 78.19%-128.46%.The detection limits were between 0.03gg/L-1.20gg/L,and the relative standard deviation was 2.15% -11.38%. GC/MS-Expert-Water System has the advantage of fast speed, smart ability, it can be applied to the detection of volatile organic compounds in water.
