FLUORESCENT X-RAY ANALYSIS METHOD OF CARBONACEOUS MATERIAL, FLUORESCENCE X-RAY ANALYZER, ITS CONTROL METHOD, AND ITS PROGRAM

摘要

PROBLEM TO BE SOLVED: To analyze quantitatively more quickly and easily an element included in a carbonaceous material by a fluorescence X-ray analysis.;SOLUTION: A fluorescence X-ray analyzer 20 determines a content of a contained element contained in the carbonaceous material by the second measuring method (for example, an ICP emission analysis method) which is different from a fluorescence X-ray analysis method, determines an intensity value of the contained element by a fluorescence X-ray measuring unit 30, stores correspondence relation information (calibration curve) between the acquired content and intensity value in an HDD 25, detects fluorescence X-ray intensity of an unknown sample, and determines the content of the contained element in the unknown sample based on the intensity value of the contained element and the correspondence relation information stored in the HDD 25. Though not having sensitivity to carbon, in the fluorescence X-ray analysis method, determination is possible by utilizing the second measuring method, and an element contained in the sample can be determined quickly and nondestructively.;COPYRIGHT: (C)2009,JPO&INPIT
