Evaluation of the main atomic number, absorption and fluorescence correction models in quantitative microanalysis

The principal LAF correction models have been tested for a set of 471 experimental values from heavy element binary specimens ( Z > 12) and another set of 116 determinations for oxides, both compiled by Love et al . New fluorescence correction models have been developed, based on a Gaussian distribution of ionizations. The atomic number, absorption and fluorescence correction models corresponding to this distribution are the best fitting ones.
