SAX, SOFTWARE FOR THE ANALYSIS OF X-RAY-FLUORESCENCE SPECTRA

A program for chemical analysis by energy-dispersive x-ray spectrometr y is described. Fluorescent multiplets are fitted to a high degree of accuracy by a method using an empirical energy-dependent peak-shape fu nction derived from the spectrometer response to well resolved standar d sample spectra, Elemental identification is accomplished via an inte ractive peak search and a complete K and L x-ray line library, Matrix correction routines for element quantification are provided for infini tely thick samples with fundamental parameters, including Compton corr ection, for thin samples and total resection (TXRF) geometry and for s emi-transparent light matrix pellets (emission-transmission method).
