The influence of the effect of sample loading heterogeneity on the accuracy of the emission–transmission technique applied in the x‐ray fluorescence analysis of specimens of intermediate thickness was studied. Various types of sample loading heterogeneities, including incompletely loaded samples, were considered. General expressions describing the accuracy of the emission–transmission method within a wide range of sample thicknesses and characteristic x‐ray energies were derived. Experiments for the verification of the theoretical predictions were also carried out for some selected test samples of known sample loading inhomogeneity.
