用于铂族元素分析的中外地质标准物质

标准物质作为地质分析的计量标准，在分析质量监控、仪器校准、方法评价和仲裁分析中发挥着重要作用。铂族元素分析一直是地质材料分析中最棘手的任务之一，铂族元素标准物质研制困难，数量少，严重影响了对铂族元素分析方法的评价和分析数据的质量监控，成为铂族金属矿产资源勘查、评价和相关研究工作的瓶颈。收集了中国及国际上现有的34个铂族元素标准物质和52个其他地球化学标准物质中的101个铂族元素定值数据。为便于使用也收集了这些标准物质中其他元素的含量信息，给出了铂族各元素按含量大小排列的信息简表以方便选择。充分利用这些标准物质对促进铂族元素分析方法研究，保证铂族元素分析数据质量，提高中国和世界铂族金属矿产资源勘查、评价及研究水平具有重要意义。

World geochemical reference materials used for the analysis of PGEs

As metrology standards, PGEs reference materials play important roles in the quality control of geoanalysis, the calibration of analytical instruments, the assessment of analytical methods and the arbitration analysis. The analysis of platinum group elements (PGEs) is one of the most challenging tasks in geoanalysis. The preparation of PGEs reference material is difficult, so there is much less PGEs reference materials in the world. This kind of situation strongly influences the correct evaluation of analytical methods and the quality of analytical results for PGEs. So it is also the bottle-neck for the investigation, evaluation and related research of PGEs minerals and natural resources. In this paper, we collected 101 certification data for PGEs in 34 PGEs reference materials and 52 normal geochemical reference materials in the world. To be convenient to use all these reference materials, the concentration informations for other elements are collected also. In addition, for the convenience of correct reference materials selection during the analysis of PGEs, all certified values for PGEs are listed in tables according to the concentration (from high concentration to low concentration) for each PGE. It is stressed that the application of those PGEs reference materials will make a great contribution to the development of analytical methods of PGEs researches, taking full use of them will be a guarantee for the reliability of the analytical results of PGEs, and an improvement for the level of investigation, evaluation and research of PGEs mineral and resouling structures of rock and ore. Explosive breccias are also the favorable pathway and reservoir space of ore fluid. The area are prospective for more ore deposits.
