本文探讨了 ICP-AES 粉末法分析大米,小麦及茶叶中微量元素的条件。试样的基体成分不同,但用粉末进样器和封闭式 ICP-arc 双放电装置,在选定的条件下,只用淀粉基体的标准即可进行分析。并用空间温度分布及抑制粒度效应等数据说明其合理性.
In this paper, ICP-AES powder analysis of trace elements in rice, wheat and tea conditions. The matrix composition of the sample varies, but with a powder injector and a closed ICP-arc double discharge device, only the starch matrix standard can be analyzed under the selected conditions. And use the space temperature distribution and inhibition of particle size data to illustrate its rationality.
