摘要： An x-ray fluorescence technique for determining a valence state of a sample. An x-ray excitation path is provided for exciting a sample with x-rays; and an x-ray detection path is provided for detecting fluorescence emitted from the sample, and focusing the emitted fluorescence to a focal spot. The detection path may include a monochromating detection optic for focusing the fluorescence; and also may include a detector on which the focal spot is focused. The precise positions of the focal spot are sensed, from which valence states of the sample can be determined; and/or the detection optic can be rocked across certain angles of incidence, to change the Bragg conditions, thereby sensing different valence states within the sample.

摘要： An x-ray system or method for exciting a sample under x-ray analysis, using a curved monochromating optic for directing a monochromatic x-ray beam from an x-ray source towards a first focal area. A second optic is positioned within, and receives, the monochromatic x-ray beam, and directs a focused x-ray beam towards a second focal area on the sample. A detector is positioned near the sample to collect radiation from the sample as a result of the focused x-ray beam. The curved monochromating optic produces a beam spot size at the first focal area larger than a beam spot size produced by the second optic at the second focal area, therefore, a beam spot size on the sample is thereby reduced using the second optic. Doubly-curved monochromating optics, and polycapillary optics, are disclosed as possible implementations of the optics.

摘要： A sample cell for an analysis instrument, having an outer body forming a sample reservoir therein; a directional fill valve disposed in an upper end of the outer body and forming an upper end of the sample reservoir, the fill valve for accepting a sample during filling, and preventing sample leakage while providing venting after filling; and a film covering a lower end of the outer body, and forming a bottom end of the sample reservoir, the film for presenting the sample to an analysis focal spot of the analysis instrument. The disclosed sample cell is especially suited for an x-ray analysis engine having a focal spot requiring alignment with the sample in the sample cell. At least one x-ray optic may be disposed in an excitation and/or detection path, requiring alignment to the focal spot, in e.g., a WDXRF or EDXRF system.

摘要： Compact, low-power-consuming systems and methods for exposing samples to high-energy radiation, for example, for exposing samples to x-rays for implementing x-ray absorption near edge analysis (XANES). The systems and methods include a low-power-consuming radiation source, such as an x-ray tube; one or more tunable crystal optics for directing and varying the energy of the radiation onto a sample under analysis; and a radiation detecting device, such as an x-ray detector, for detecting radiation emitted by the sample. The one or more tunable crystal optics may be doubly-curved crystal optics. The components of the system may be arranged in a collinear fashion. The disclosed systems and methods are particularly applicable to XANES analysis, for example, XANES analysis of the chemical state of chromium or another transition metal in biological processes.

摘要： A method and device for cooling and electrically-insulating a high-voltage, heat-generating component, for example, an x-ray tube (1105) for analyzing fluids by means of x-ray fluorescence. The device includes an x-ray source (1100) including an x-ray tube (1105) having improved heat-dissipating properties due to the thermal coupling of the x-ray tube with a thermally-conductive, dielectric material (1150). The device may include a base assembly (1135) mounted to the component for conducting heat away from the component while electrically isolating the component. In one aspect of the invention, the base assembly includes two copper plates (1140, 1145) separated by a dielectric plate (1150). The dielectric plate minimizes or prevents the leakage of current through the base assembly (1135). One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.
