摘要: 本文测定了Ca、Cd、Mg、Mn、Zn 5种元素电离度在1CP中的垂直空间分布,观察了基体元素及操作条件(正向功率与载气流量)对电离度的影响,结果表明,元素的电离度与ICP的激发特性没有直接的联系;基体元素及操作条件对电离度影响很小。

关键词: ICP-AES, 电离度, 基体效应

Abstract: Axial profiles of the degree of ionization of Ca,Cd,Mg,Mn,Zn were determined. The influences of forward power and carrier gas flow on the degree of analyte ionization were observed. Theresults show that the degree of the analyte ionization is not related to the excitation characteristic ofICPdirectly. The influence of matrix elements on the degree of analyte ionization is insignificant.

Key words: ICP-AES, Degree of ionization, Matrix effect
