Patent ID: 6885726

Claim:
A fluorescent X-ray analysis apparatus comprising: an X-ray generation source for radiating a beam of primary X-rays; plural spectroscopic elements having inner surfaces and circularly arranged so that their inner surfaces describe a circle centered on an optical axis of the beam of primary X-rays and for monochromatizing the beam of primary X-rays into a monochromatic beam of primary X-rays and condensing the beam of primary X-rays on a surface of an object irradiated by the beam; spectroscopic element position adjusting means for adjusting positions of the plural spectroscopic elements; a secondary X-ray detector for detecting secondary X-rays radiated from a surface of the irradiation object upon irradiation with the monochromatic beam of primary X-rays; secondary X-ray detector position adjusting means for adjusting position of the secondary X-ray detector; irradiation object surface position detecting means for detecting position of the surface of the irradiation object radiating the secondary X-rays; and control means for adjusting the positions of the plural spectroscopic elements by the spectroscopic element position adjusting means to condense the monochromatic beam of primary X-rays on the surface of the irradiation object, based on the position of the surface of the irradiation object detected by the irradiation object surface position detecting means.
