    • PROBLEM TO BE SOLVED: To separate properly a fluorescent X-ray peak waveform from a background waveform, even in the case of a spectrum existing near an inflection point at which the background waveform is changed suddenly.SOLUTION: Each intensity of the background waveform and the fluorescent X-ray peak waveform is changed so as to reproduce excellently a measured waveform by using a typical background waveform, a fluorescent X-ray peak waveform whose intensity is desired to be determined, and a plurality of detected fluorescent X-ray peak waveforms existing in the periphery of the peak. In this fluorescence X-ray analyzer, the fluorescent X-ray peak waveform and the background waveform are separated from a completed spectrum.
