BS EN ISO 18635:2016规定了一种定量测定短链和的方法 多氯正构烷烃，也称短链多氯烷烃（SCCP） 碳键范围，n-C10至n-C13，包括在含有氯质量分数（“含量”）的混合物中 在50%到67%之间，包括约8000种同类中的约6000种。本方法适用于沉积物和悬浮物中短链氯化石蜡总量的测定 （颗粒）物质、污水污泥和土壤的气相色谱-质谱分析 电子捕获负电离（GC-ECNI-MS）。根据基质和GC-ECNI-MS的检测能力，该方法可用于 含有0,03µg/g至3µg/g短链氯化石蜡的样品。警告-使用本文件的人员应熟悉正常的实验室实践。 本文件并非旨在解决与其相关的所有安全问题（如有） 使用用户有责任建立适当的安全和健康实践，并 确保遵守任何国家监管条件。重要事项——按照本文件进行测试是绝对必要的 由合格的员工执行。交叉引用:ISO 5667-12ISO 5667-13ISO 5667-17ISO 8466-1ISO 12010ISO/TS 13530ISO 5725-2购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS EN ISO 18635:2016 specifies a method for the quantitative determination of the sum of shortchain polychlorinated n-alkanes also known as short-chain polychlorinated paraffins (SCCPs) in the carbon bond range, n-C10 to n-C13, inclusive in mixtures with chlorine mass fractions ("contents") between 50 % and 67 %, including approximately 6,000 of approximately 8,000 congeners.This method is applicable to the determination of the sum of SCCPs in sediment and suspended (particulate) matter, sewage sludge, and soil using gas chromatography-mass spectrometry with electron capture negative ionization (GC-ECNI-MS).Depending on matrix and the detection capabilities of the GC-ECNI-MS, the method can be applied to samples containing, e.g. 0,03 µg/g to 3 µg/g sum of SCCPs.WARNING - Persons using this document should be familiar with normal laboratory practice.
