A simple method to evaluate the matrix effects in X‐Ray fluorescence analysis

Abstract

Abstract In X‐ray fluorescence analyses, the matrix effects can be evaluated by computing appropriate coefficients. Utilising powder pellets of samples artificially prepared, a method for computing the matrix effects coefficient of H 2 O, Na 2 O, MgO, Al 2 O 3 , SiO 2 , K 2 O, CaO, TiO 2 , Fe 2 O 3 for the analytical lines of thirteen elements: vanadium, chromium, nickel, copper, zinc, gallium, rubidium, strontium, zirconium, barium, lanthanum, cerium and lead is described. The computed coefficients have been used to analyse six international rock standards (the U.S. Geological Survey Standards: G‐2, GSP‐1, AGV‐1, BCR‐1, PCC‐1, DTS‐1).
