Patent ID: 7634053

Claim:
A fluorescent X-ray analysis apparatus quantifying an aimed element contained in a sample, which possesses: a sample base stationarily supporting the sample, an X-ray source directed to a predetermined irradiation point and irradiating a primary X-ray to an irradiation face of the sample supported by the sample base at the predetermined irradiation point, a detector directed toward the predetermined irradiation point and detecting a fluorescent X-ray generated from an inspection face of the sample to which the primary X-ray has been irradiated, and sample holding tools differently configured such that the sample holding tools are selectively set in the sample base to stationarily support the sample at the predetermined irradiation point respectively in a 1st inspection position and in a 2nd inspection position based on a type of the sample, wherein: the 1st inspection position is a position in which the irradiation face and the inspection face at least partially overlap each other in a single surface of the sample, and the 2nd inspection position is a position in which the irradiation face and the inspection face reside in different surfaces of the sample.
