METHOD FOR CALCULATING INTENSITY OF SPECTRAL LINE OF FLUORESCENT X-RAY

摘要

PROBLEM TO BE SOLVED: To more accurately calculate the intensities of the spectral lines of different elements contains in the same peak of a spectral waveform with a fluorescent X-ray analyzer. SOLUTION: By finding the position CP and intensity IP of a peak P containing the spectral lines PA and PB of different elements A and B in advance, the positions CA and CB of the wavelength and intensities IA and IB of the spectral lines PA and PB are estimated and the shapes of the spectral lines PA and PB functionally approximated based on the estimated values. Then the intensities IPA and IPB of the spectral lines PA and PB at the position of the peak CP are estimated and corrected by constantly maintaining the ratio between the intensities IPB so that the sum of the intensities IPA and IPB many coincident with the peal intensity IP and the corrected values IPA' and IPB' are outputted as the intensity values of the spectral lines A and B.
