Abstract

The ISO draft proposal for sampling and analysis of chlorinated hydrocarbon solvent vapors in workplace atmospheres (ISO/TC 146/SC 2/WG4 N41) has been evaluated by means of a round-robin test. For this purpose, the repeatability and reproducibility for the determination of tetrachloromethane, trichloromethane, 1,1,1-trichloroethane, trichloroethene were determined at three concentration levels. Furthermore, parameters such as breakthrough and loss on storage were determined. Samples were taken by 11 participants from six countries. After statistical evaluation of the results, it appeared that improvements were necessary for the determination of tetrachloromethane and trichloromethane. For the other three compounds, repeatability and reproducibility were sufficient. Possible error sources and possibilities for improvements are discussed.

摘要

国际标准化组织（ISO）关于工作场所空气中氯代烃溶剂蒸气采样与分析的提案草案（ISO/TC 146/SC 2/WG4 N41）已通过循环试验进行了评估。为此，在三个浓度水平下测定了四氯化碳、三氯甲烷、1,1,1 - 三氯乙烷、三氯乙烯测定的重复性和再现性。此外，还测定了诸如穿透率和储存损失等参数。来自六个国家的11名参与者采集了样本。对结果进行统计评估后发现，四氯化碳和三氯甲烷的测定方法有必要改进。对于其他三种化合物，重复性和再现性是足够的。文中讨论了可能的误差来源和改进的可能性。
