Extract

Spectrum processing is a critical step in energy-dispersive X-ray fluorescence analysis, with very strong influence on the final performance of the method. Spectrum processing includes two major procedures: (i) preliminary processing (which deals mainly with reduction of random and systematic noise); and (ii) evaluation of peak parameters (most often peak area, and in some cases also peak position, amplitude and width). Preliminary processing solves two main problems: (i) search and correction of erroneous channel contents (outlier values); and (ii) random noise reduction. Several procedures for search and correction of outlier values have been proposed for Raman, gamma and X-ray spectra.
