FLUORESCENCE X-RAY ANALYSIS DEVICE

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. 【課題】十分にＸ線を遮蔽しながら高感度に蛍光Ｘ線を測定することができ、低コストで板状試料の判別が可能となる蛍光Ｘ線分析装置を提供する。【解決手段】蛍光Ｘ線分析装置は、試料箱１に廃品パネル（板状試料）Ｐを収納して密閉し、試料箱１の底部２に設けてある窓部２１を通してＸ線の照射及び蛍光Ｘ線の検出を行い、廃品パネルＰにヒ素等の特定の元素が含まれているか否かを判定する。試料箱１の一側面は開閉部３となっており、廃品パネルＰは底部２の上面から浮いた状態で、複数のボール２２で支持される。複数のボール２２によって廃品パネルＰの出し入れ及び位置調整が容易となり、廃品パネルＰが接触して底部２が破損することが防止される。試料箱１でＸ線が遮蔽され、検出部５は廃品パネルＰに近接して高感度で蛍光Ｘ線を測定する。廃品パネルＰを搬送する搬送装置を利用する従来技術に比べて低コストな蛍光Ｘ線分析装置が実現される。【選択図】図２
