标准摘要
[中文适用范围]： 本部分ISO 16918规定了一种使用电感耦合等离子体质谱法（ICP-MS）分析钢和铁中锡（Sn）、锑（Sb）、铈（Ce）、铅（Pb）和铋（Bi）痕量元素的方法。该方法适用于以下质量分数范围（µg/g）的痕量元素：Sn: 5 µg/g 至 200 µg/g；Sb: 1 µg/g 至 200 µg/g；Ce: 10 µg/g 至 1 000 µg/g；Pb: 0.5 µg/g 至 100 µg/g；Bi: 0.3 µg/g 至 30 µg/g。使用ICP-MS测定痕量元素时的干扰列于附录B。 [外文原描述]： ISO 16918-1:2009 specifies a method for analysing steel and iron for the trace element determinations of Sn, Sb, Ce, Pb and Bi using inductively coupled plasma mass spectrometry (ICP-MS). The method is applicable for trace elements in the mass fraction ranges (µg/g) as follows: Sn: 5 µg/g to 200 µg/g; Sb: 1 µg/g to 200 µg/g; Ce: 10 µg/g to 1 000 µg/g; Pb: 0,5 µg/g to 100 µg/g; Bi: from 0,3 µg/g to 30 µg/g. Interferences in the determination of trace elements using ICP-MS are listed in Annex B.
