关于铂族元素分析精度要求的讨论

    A review on the precision requirement for the determination of platinum-group elements.

    • 摘要: 列举了1972年、1978年、1988年、1994年、2002年和2006年6次制订、修订的质量管理制度、规定、规范(地质矿产行业标准)中关于铂族元素分析精度的规定和要求,评介了6个质量管理文件中对铂族元素分析精度要求的变化,计算、统计了中国与世界铂族元素标准物质标准值定值数据的精度。最后在上述资料的基础上讨论了当今铂族元素分析和标准物质标准值定值的精度要求问题,并据此提出了相关的建议。

       

      Abstract: In this paper, the specifications and requirements of testing quality management for the determination of platinum group elements in geological laboratories (ministerial standard of geological minerals) issued successively in 1972, 1978, 1988, 1994, 2002 and 2006. The change of the precision requirements for the determination of platinum group elements in those specifications is reviewed. In addition, the precision for the certification of platinum group element reference materials developed by China and the other countries in the world is statistically calculated, and finally on the basis of the above information, the precision requirements for the determination of platinum group elements and preparation of platinum group elements reference materials are discussed and the related suggestions are presented.
