QUANTITATIVE ANALYSIS METHOD FOR SAMPLE SOLUTIONS USING X-RAY FLUORESCENCE ANALYZER

摘要

PROBLEM TO BE SOLVED: To provide a method for using an X-ray fluorescence analyzer to highly accurately quantitatively analyze the content of a designated element present in a measured solution in a trace quantity, without requiring a high skill level.SOLUTION: Provided is a quantitative analysis method using an X-ray fluorescence analyzer, comprising the steps of: impregnating a designated quantity of a solution of the measurement target into a medium and then drying it; mounting a jig in a side not facing an X-ray tube for the medium, which jig does not contain the measurement target and internal reference element as its constituent elements, nor emit fluorescent X rays with wavelengths interfering with the detection of fluorescent X rays emitted by the measurement target and the internal reference element, and which thermally and mechanically prevents the medium from deforming by heat radiated from the X ray tube; and mounting the medium and the jig to the X-ray fluorescence analyzer.SELECTED DRAWING: Figure 4
