Several mathematical models for correcting x‐ray fluorescence intensities are proposed in the literature. However, it is not always easy for the analyst to choose the best one for a particular case. Therefore a modular program has been written to compare automatically mathematical models for quantitative x‐ray spectrometry with the object of determining the best conditions of analysis (models, number and nature of interfering elements and matrix effects). The graphic display of the standard deviation of the standards as a function of the interfering elements used in the correction simplifies and accelerates the interpretation of the matrix effects.
