摘要： In the present invention, a fluorescent X-ray analysis is made for a sample such as a liquid fuel including an object component such as sulfur. A background related to scattered X-rays and a system peak is subtracted from a fluorescent X-ray intensity of the object component, which is obtained from a spectrum acquired by the fluorescent X-ray analysis. A correction corresponding to the composition of the sample is performed for the fluorescent X-ray intensity obtained by subtracting the background. A calibration curve representing the relation between a value, which is obtained after performing the correction for the fluorescent X-ray intensity obtained by subtracting the background, and a concentration of the object component is preset. The concentration of the object component in the sample is calculated on the basis of the calibration curve.

摘要： In a sample cell that is sealed with an X-ray transmission sheet after a sample such as a liquid fuel or the like is contained therein, when an internal pressure is increased, a cup end surface is deformed so as to increase an internal capacity of the sample cell before the X-ray transmission sheet serving as a window part is expanded. The cup end surface is formed by folding a film-like material and, when the internal pressure of the sample cell is increased, the cup end surface is unfolded outwardly of the sample cell to increase the internal capacity of the sample cell. The increase in pressure is relieved by the increase in capacity, and the expansion of the X-ray transmission sheet is thereby prevented.

摘要： This invention provides an X-ray analysis apparatus and method capable of simply and accurately determining the position of analysis in a sample from an optical image of it without lowering the sensitivity and/or the spatial resolution in light element analysis. The X-ray analysis apparatus of the present invention irradiates a sample with X-rays narrowed down by means of an X-ray guide member from above the sample in which said sample is directly irradiated with X-rays from said X-ray guide member and an optical image of said sample is obtained in the direction coaxial with said X-ray guide member.

摘要： An X-ray convergence element and an X-ray irradiation device including the X-ray convergence element are provided. The X-ray convergence element can extend a working distance from an exit-side opening end thereof to a specimen, and can perform analysis of the specimen with rough surface, a fluorescent X-ray analysis, and a X-ray diffraction analysis, regardless of a size of the specimen. An X-ray blocking member 23 is provided with three supporting members 233 for supporting the X-ray blocking member 23, which extend from an annular member 232 having approximately the same diameter as a diameter of an entrance-side opening end (outer diameter of a capillary 20) toward the center of the X-ray blocking member 23 to fix the annular member 232 to the capillary 20. The annular member 232, the supporting members 233, and the X-ray blocking member 23 are integrally formed of a metal that shields X-rays, such as tantalum, tungsten, or molybdenum. A dimension of the X-ray blocking member 23 in the axial direction (thickness) is set to be sufficient for blocking X-rays.
