Abstract

A X-ray fluorescence spectrometer of the present invention simultaneously generates an analytical pulse-height width profile and a narrow pulse-height width profile that are distributions of intensities of secondary X-rays () against scan angles (θ) set by an interlocking unit () on the basis of a differential curve which is output by a multichannel pulse-height analyzer (), as well as a predetermined analytical pulse-height width for an analytical line that is a primary reflection line and a predetermined narrow pulse-height width that is narrower than the analytical pulse-height width. Identification of the analytical lines is performed for the analytical pulse-height width profile and the narrow pulse-height width profile, and any analytical line identified only in the narrow pulse-height width profile is added to the analytical lines identified in the analytical pulse-height width profile to obtain an identification result of the analytical lines.
