微量分析用标准参考物质IAEA—386牛肝的研制

Preparation of reference material LAEA-386 Bovine Liver for micro-analytical techniques

介绍了国际原子能机构（IAEA）用于微量分析技术标准参考物质IAEA－386牛肝的制备过程。激光粒度检测结果表明粉末牛肝的粒度平均值为22μm，对应于分布最大峰处的粒度直径约为35μm。出于质控和数据评介的需要，它的均匀性测定和定值工作将由IAEA在国际范围内组织各国分析实验室进行。

A bovine liver candidate reference material specially for micro--analytical techniques is prepared. The laser particle size test shows that the median particle's diameter is 22 μ m and the size corresponding to the largest peak in the distributions is about 35 μm. For reasons of quality control and better assessment of resulting data, its certification campaigns on world--wide basis will be organized by IAEA.
