- 1 - Abstract The present invention is directed to a fluorescent X-ray method for analyzing a solution specimen. A parti- cular quantity of the solution specimen to be analyzed is impregnated into a thin porous sheet, for example by a dripping method, and the sheet is dried by evaporating the solvent. The sheet is placed on an appropriate holder in a vacuum atmosphere or an atmosphere of helium gas, so that primary X-rays are irradiated and the wavelength or the intensity of the fluorescent X-rays generated from the solute remaining in the sheet may be detected. The strength of the solution may be changed by concentration or by dilution, so that an adequate intensity of the fluorescent X-ray may be generated. The specimen sampler is made of a porous sheet material, to which the solution specimen to be analyzed is impregnated and dried so that only the solute of the solution remains in the sheet. To the circumferential edge of the sheet is attached a sup- port, so that the central portion of the porous sheet is sufficiently spaced from the circumferentially provided support.
