CONFOCAL X-RAY FLUORESCENCE ANALYSIS OF SAMPLES FORMED FROM HOMOGENEOUS LAYERS: COMPARISON OF SIMULATIONS WITH EXPERIMENTAL MEASUREMENTS.

Confocal X-ray fluorescence analysis is a non-destructive method that enables the determination of the elements depth distribution in the examined sample. Accurate determination of the elements depth distributions in various samples from measured depth profiles is very demanding, and generally, a valid procedure has not been developed as yet. The main aim of this work was to design and test a universal simplified calculation procedure, which would allow the calculation of the approximate shape of the depth profiles for a sample formed from layers of a given thickness and composition.
