Abstract Some new intensity correction models are derived based on the Lanchance–Traill set of equations and the nomographic interpretation of matrix effects. The correction models proposed in the present paper are checked experimentally using the artificial samples containing iron, zinc and lead oxides in a natural dolomite. Experiments were carried out on a multi‐channel X‐ray spectrometer with a Si(Li) detector and a 238 Pu radioactive source. The accuracy of determination achieved with the use of correction equations presented here is compared with the accuracy attinable after using several mathematical procedures known from the literature. The results presented show the great applicability of the proposed methods.
