ABSTRACT:
There is provided a fluorescent X-ray analysis apparatus in which a detection lower limit has been improved by reducing an X-ray generating subsidiarily and detected. The fluorescent X-ray analysis apparatus is one which possesses an X-ray source irradiating a primary X-ray, and a detector in which a collimator having a through-hole in its center part has been placed in a front face, and in which, by the detector, there is detected a primary fluorescent X-ray which generates from a sample by irradiating the primary X-ray to a sample, and passes through the through-hole of the collimator. The X-ray source and the detector are disposed while adjoining the sample, and an irradiated face of the X-ray source or the detector, to which a primary scattered ray having generated by the fact that the primary X-ray scatters in the sample and the primary fluorescent X-ray having generated from the sample are irradiated, is covered by a secondary X-ray reduction layer reducing a secondary scattered ray and a secondary fluorescent X-ray, which generate by irradiations of the primary scattered ray and the primary fluorescent X-ray.
