| Abstract: | The fundamental principle of atbmic ionization and excitation models applied in ICP-AES primary expert system was described. The validity of non--LTE processes and nec- essary databases was demonstrated. Boltzmann plots of Ca and Mg with non-LTE simulation showed that the Boltzmann temperature might not be represented with only one value. The reliability of the established AES excitation model has been proved by the comparison with experimental Boltzmann plots. |
