DIFFERENT-SHAPE SAMPLE HOLDER FOR UNDERFACE IRRADIATION FLUORESCENT X-RAY ANALYSIS, AND UNDERFACE IRRADIATION TYPE FLUORESCENCE X-RAY SPECTROMETER EQUIPPED THEREWITH

摘要

PROBLEM TO BE SOLVED: To provide a sample holder for underface irradiation fluorescent X-ray analysis used for the fluorescent X-ray analysis of various samples having different shapes, and an underface irradiation type fluorescence X-ray spectrometer equipped therewith, to effectuate thereby analytical work for the different shape samples, and to reduce thereby an expense therefor.;SOLUTION: This different-shape sample holder for the underface irradiation fluorescent X-ray analysis used for irradiating an underface of the sample with a primary X-ray to conduct the fluorescent X-ray analysis is provided with a frame body 2, four holding arms 11-14 having a support part 31 supported rotatably onto the frame body 2 in one end, having a sample abutting part 41 abutting on the underface Sa of the sample and a grasping part 51 for grasping a sideface of the sample in the other end, and having an arm part 61 extended from the support part 31 to the grasping part 51, the holding arms 11-14 are supported on the frame body 2 by support parts 31-34 to position an abutting face abutting on the underface Sa of the sample in each abutting part, on the same plane, and the sample S is held in an inner side of a circumference of the frame body 2, by the abutting parts 41-44 and the grasping part 51-54.;COPYRIGHT: (C)2008,JPO&INPIT
