X-RAY ANALYZER

To provide an X-ray analyzer capable of suppressing leakage of X-rays at the time of replacement of a sample.SOLUTION: An X-ray analyzer 1 is configured to block X-rays, and includes: an analysis chamber 300 for performing analysis of a sample by X-rays; an opening/closing mechanism 600 for opening/closing the analysis chamber; an X-ray source 210 that is disposed in the analysis chamber and irradiates a sample S with X-rays; a detector 220 that is disposed in the analysis chamber and detects fluorescent X-rays emitted from the sample; a storage chamber 114 that is provided outside the analysis chamber 300 and houses the sample; and a storage chamber opening/closing mechanism 400 for opening/closing the storage chamber 114 without opening/closing the analysis chamber 300.SELECTED DRAWING: Figure 1 【課題】試料の交換時におけるＸ線の漏洩を抑制可能なＸ線分析装置を提供すること。【解決手段】Ｘ線分析装置１は、Ｘ線を遮断するように構成されており、Ｘ線による試料の分析が行われる分析室３００と、分析室を開閉する開閉機構６００と、分析室内に配置されており、試料ＳにＸ線を照射するＸ線源２１０と、分析室内に配置されており、試料から放出された蛍光Ｘ線を検出する検出器２２０と、分析室３００外に設けられており、試料が収容される収容室１１４と、分析室３００を開閉することなく収容室１１４を開閉する収容室開閉機構４００と、を備える。【選択図】図１
