The use of a fundamental parameter method for effecting matrix corrections in quantitative x-ray spectrochemical analysis is described. A versatile computer program calculates composition directly from measured intensities. Variations in the basic approach are employed in the analysis of a series of sulfide and oxide samples. The Applied Research Laboratories multi-channel x-ray quantometer (MXQ) is briefly described.
