PROBLEM TO BE SOLVED: To provide a fluorescence X-ray analysis device that enables a measurement of a fluorescence X-ray with high sensitivity as sufficiently shielding the X-ray, and enables a determination of a tabular sample in low costs.SOLUTION: A fluorescence X-ray analysis device is configured to: house a waste panel (tabular sample) P in a sample box 1 and tightly seal the waste panel P therein; radiate an X-ray through a window part 21 provided in a bottom part 2 of the sample box 1 and detect a fluorescence X-ray therethrough; and determine whether a specific element such as arsenic and the like is contained in the waste panel P. One side face of the sample box 1 is an opening/closing part 3, and the waste panel P is supported by a plurality of balls 22 in a state where the waste panel P floats from an upper face of the bottom part 2. The plurality of balls 22 makes it easier to take the waste panel P in and out, and facilitates a position adjustment of the waste panel P, which prevents a damage of the bottom part 2 by the waste panel P contacting with the upper face. The X-ray is shielded by the sample box 1, and the detection unit 5 is configured to get proximity to the waste panel P to measure a fluorescence X-ray with high sensitivity. In comparison with a conventional art using a conveyance device conveying the waste panel P, the low cost fluorescence X-ray analysis device is enabled to be attained. |
