摘要
标准物质的特性量值应该具备溯源性。然而地质标准物质溯源性的建立往往是很困难的。对痕量元素量值溯源的若干难点进行了讨论 ;提出了建立标准物质研制的质量体系的建议并就相关问题进行了阐述 ;应重视量值的信息反馈 ,提高定值的质量。
The property values of standard reference materials should be of traceablity. However, the establishment of the traceablity for geologic certified reference materials is more difficult. In this paper, some tricky points of traceablity for trace elements in GCRMs were discussed. A quality control system for reference material study was proposed and some relative problems were also discussed.
