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
