The Mathematical Correction Of Matrix Effects In The Analysis Of Soda-Lime-Silica Glasses By Xrf

The accurate analysis of materials over a wide range of compositions by x-ray fluorescence techniques (xrf) requires an effective method for the correction of absorption effects within the sample due to variations in the composition of the matrix. A mathematical method of correcting for these matrix effects based on tabulated values of the mass absorption coefficients of elements has been evaluated on a series of soda-lime-silica glasses containing the oxides of sodium, calcium, silicon, aluminium, magnesium, potassium, iron, zirconium, titanium, arsenic, sulphur and antimony.
