6061和2A12铝合金光谱分析用标准物质的研制

Development of 6061 and 2A12 Aluminum Alloys Reference Materials for Spectral Analysis

介绍了铝合金用标准物质的研制过程,该标准物质均匀性稳定性良好,经多家实验室采用ICP-AES、AAS、ICP-MS、光度法等方法进行定值分析,确定了Si、Fe、Cu、Mn、Mg、Cr、Ni、Zn、Ti九个元素的认定值和不确定度,有效期限定为10a。

This paper introduces the development of aluminum alloy reference materials for spectroscopic analysis.The reference materials have good uniformity and stability.The certified value and uncertainty of nine elements Si,Fe,Cu,Mn,Mg,Cr,Ni,Zn and Ti are determined by ICP-AES,AAS,ICP-MS and spectrophotometry in many laboratories.The validity period is limited to ten years.
