中文摘要: |
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。 |
英文摘要: |
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 parameters 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. |
