摘　　要：调研分析了国内水中氯苯类化合物的常用分析技术应用现状,对吹扫捕集-气相色谱/质谱联用法可量化的精密度与准确度质量控制指标开展研究。针对水中氯苯、1,2-二氯苯、1,4-二氯苯、三氯苯等4种氯苯类化合物的实际样品平行测定相对偏差、空白加标回收率及平行样相对偏差、实际样品加标回收率及平行样相对偏差等指标,通过实验室内方法优化和参数确定,以及国内多家实验室质控数据采集与统计分析,经文献数据比对,获得了不同置信区间下系统性和适用性良好的量化质控指标。This article studies the quality control indices which can be quantified such as bias , precision and accuracy in determination of chlorobenzene compounds in water using purge＆trap -GC/MS.The quantified quality control indices were drawn in different confidence interval through the analysis of optimization methods and parame -ters in laboratory , acquisition and statistical analysis of domestic quality control data from several laboratories .The applicability of these quantified quality control indices is good through comparing with literature data .
