も招く。However, in the case of the above-mentioned conventional example in which a binder is added to a powder sample, mixed and then pressed and molded, X-ray analysis is performed. Also needs to be selected appropriately so as not to adversely affect the X-ray analysis, and the operation becomes complicated. In this case, since the sample is diluted with the binder, a dilution error and a decrease in sensitivity of X-ray analysis are caused.

る。According to the sample holder device for X-ray analysis of the first aspect, the powder sample is accommodated in one end opening side in the sample cup in a state sandwiched between the resin cover sheet and the porous material,
Since the porous material is pressed against the sample by the elastic holder, the analysis surface of the powder sample covered with the resin cover sheet is stable, and the X-ray is irradiated by the top-irradiation type fluorescent X-ray analyzer without being pressed. Can be analyzed. Further, since the powder sample is degassed via the porous material, there is no possibility that the powder sample is scattered even in a vacuum, and X-ray analysis can be performed in a vacuum. Further, since the sample is not diluted with the binder, there is no dilution error, the sensitivity is improved, and accurate analysis can be performed.

The powder sample is sandwiched between the resin cover sheet and the porous material and accommodated in one end opening side in the sample cup, and one end of the sample cup with the cover sheet attached thereto is engaged with the retaining portion of the sample holder by the elastic holder. And the porous material is pressed against the sample by the elastic holder, so that the analysis surface of the powder sample covered with the cover sheet is stable, and the top surface irradiation type fluorescent X-ray analyzer is not pressed. Enables X-ray analysis. Further, since the powder sample is degassed via the porous material, there is no possibility that the powder sample is scattered even in a vacuum, and X-ray analysis can be performed in a vacuum. Also, since the sample is not diluted with the binder, there is no dilution error.
