| 摘 要： | 使用高纯物质人工合成的方法,成功研制了4个人工标准物质。该系列标准物质涵盖了钛、钒、锰、铬、钴、镍、铜、锌、砷、铅、铋、铷、锶、钇、锆、铌、钼、钨、钕、钽、铪、镱、锡、钡、铯、镓、锗、镧、铈等29个元素,不同分析元素的含量范围可扩大到0.00x%~8%。该系列标准物质不仅可以补充自然标准的不足,扩展校准曲线含量范围,而且能够修正干扰系数,解决了准确计算分析元素之间的干扰和仪器校正带来的实际困难。用4个人工标准物质取代单元素人工标准的配制方法,减少标准数量,节约了资源以及标准配制的时间,避免了X射线荧光光谱分析工作者的重复劳动,提高了工作效率。研制的4个标准物质经检验均匀性和稳定性良好,量值准确可靠,已被国家质量监督检验检疫总局批准为国家一级标准物质。

| Abstract: | Four reference materials were synthesized using high-purity materials.The certified values for 29 elements,including Ti,V,Mn,Cr,Co,Ni,Cu,Zn,As,Pb,Bi,Rb,Sr,Y,Zr,Nb,Mo,W,Nd,Ta,Hf,Yb,Sn,Ba,Cs,Ga,Ge,La,Ce were provided in the four reference materials.The content range for different elements in these reference materials was 0.00x%~8%.The use of the four reference materials could modify and adjust the interference coefficients,which settled the troubles of interference calculation among elements and emendation of the instrument.Compared to the use of single element reference materials,less number of reference materials could be used and higher analysis efficiency could be obtained.The homogeneity and stability were tested for the reference materials and the results showed that these reference materials were homogeneous and stable.These reference materials have been approved as the national reference materials by General Administration of Quality Supervision & Inspection and Quarantine of China. |
