A simple, effective method is described, which permits accurate quantitative analysis of thin samples applying the X-ray fluorescence technique. The presented computer program (DECON) uses a weighted linear fitting of the set of computer generated reference spectra. The background function is included in the fitting process and approximated as a ninth-order polynomial. The precise calibration procedure, based on the fitting of high, ealisy used in several applications of the analysis of biomedical and environmental samples.
