水质

[中文适用范围]： 本文件规定了电感耦合等离子体质谱法 (ICP-MS) 的原理，并提供了使用该技术测定水、污泥消解物和沉积物（例如 ISO 15587-1 或 ISO 15587-2 中所述的水消解物）中元素的一般要求。通常，测量是在水中进行的，但也可以引入气体、蒸汽或细颗粒物。本文件适用于使用 ICP-MS 进行水溶液分析。元素的最终测定在针对每个元素系列和基质的单独国际标准中描述。本文件的各个条款引导用户参考这些指南，以了解方法的基本原理和仪器的配置。 [外文原描述]： This document specifies the principles of inductively coupled plasma mass spectrometry (ICP-MS) and provides general requirements for the use of this technique to determine elements in water, digests of sludges and sediments (e.g. digests of water as described in ISO 15587-1 or ISO 15587-2). Generally, the measurement is carried out in water, but gases, vapours or fine particulate matter can be introduced too. This document applies to the use of ICP-MS for aqueous solution analysis. The ultimate determination of the elements is described in a separate International Standard for each series of elements and matrix. The individual clauses of this document refer the user to these guidelines for the basic principles of the method and the configuration of the instrument.
