Extract

Trace element determination by X-ray fluorescence spectrometry is subject, like almost all instrumental analytical techniques, to systematic errors, also known as matrix effects. This paper deals with the determination of mass absorption coefficients (MACs), using Compton peak intensities, for the correction of matrix effects arising only from elemental absorption in the sample.

When absorption effects are significant the relationship between net analyte peak intensity and concentration will no longer be constant, and corrections will be necessary for accurate analyses.
