Abstract
System, method and computer program product for determining mass fractions of one or more elements in a test sample based on a measurement with a wave-length dispersive x-ray fluorescence (WDX) spectrometer measuring gross intensities associated with respective elements with to-be-determined mass fractions (MFi) in the test sample. A mass fraction module determines mass fractions (MFi) by using a calibration equation (CE1) with the respective measured gross intensity and a respective calculated scattering efficiency as inputs. The calibration equation (CE1) associates net intensities of characteristic fluorescence lines of the sample elements with respective mass fractions. The net intensity for a particular peak is obtained by subtracting a respective calculated scattering efficiency times a scaling factor from the calibration equation (CE1) from the measured gross intensity of the particular peak. The elemental composition of the test sample is determined either via an iteration module or via an EDX quantification module.
