抄録

A preparation method of a solution sample in fluorescent X-ray spectroscopy has been developed. There is a considerable constraint in the drying and dropping process in the conventional method using a specially designed filter paper. In the present method for fixing filter paper on a sample holder, no problems, such as distortion or breaking of the filter paper, was caused when a sample solution was heated for drying. By reducing the thickness of the filter paper, the absorption of fluorescent X-rays could be suppressed for light elements. For heavy elements, it was possible to increase the quantity of the dropping sample by increasing the thickness and area of the filter paper. In addition, by using a separating filter paper or a functional filter paper, such as ion-exchange filter paper, it is possible to collect only the specified element. A performance enhancement of the analytical system and on extension of the fields of application can be expected.
