Abstract
An apparatus or method determines an elemental composition of a sample by scanning a sample using a PXRF spectrometer, receiving a PXRF spectra from the PXRF spectrometer, baseline correcting and smoothing the received PXRF spectra, extracting a Kα emission line of one or more elements from the baseline corrected and smoothed PXRF spectra from the PXRF spectrometer, determining the elemental composition of the sample using a predictive model that relates the Kα emission line of the one or more elements to the elemental composition of the sample, and providing the elemental composition of the sample to the one or more input/output interfaces.
