With the help of a fundamental parameter program, the matrix e β ect of multi-component complex samples and the composition of each elementΓs X-ray Γuorescence intensity were calculated. A mathematical model for correcting the multi-component matrix e β ect was deduced theoretically. It provides two m

In quantitative EDXRF analysis of ancient metallic objects two main difficulties arise : i) how to Γnd out the correction factors for the irregular shape or relief e β ects and ii) how to measure the true composition of the bulk metal under the surface patina. In the case of coins, taken as a typical
A method of analyzing mixtures of APIs and excipients using X-ray powder diffraction is described. It uses a simple algorithm based on linear regression in which the pure component phases are fitted to the mixture pattern using linear least squares. Unlike many methods that use only the peaks in the
