[Evaluation on analysis of six minerals in ten biologic materials].
The study is to evaluate the content of Mn, Cu, Fe, Zn, Mg and Ca in 10 sorts of biological material. The standard methods (GB/T5009.13,14,90,92 - 2003) were taken to measure. Two standard reference materials were used to control the accuracy of analyses. And chemical uncertainty was used to evaluate 6 minerals content. The results described the six minerals contents for the ten biologic materials. The study provided the necessity conditions to be used as standard reference materials for these 10 biological materials.
