Mathematical Correction Of Matrix Effects In The X-Ray Fluorescence Analysis Of Soda-Lime-Silica Glasses.

A mathematical method, employing tabulated values of mass absorption coefficients, was tested on a set of soda-lime-silica glasses containing the oxides twelve elements: Si,Na,Ca,Mg,Al,Fe,K,Zr,Ti,As,S,Sb. The method proved effective for all except the last four elements. other sources of error were present for S and Sb. For Sb, a second correction for the influence of Ca proved effective. For all elements this method gave results comparing favourably with those obtained by standard chemical methods.
