摘要： An x-ray fluorescence technique for detecting, e.g., the level of arsenic in a sample of water or body fluid. Arsenic and lead are expected to fluoresce in a first energy band and lead is expected to also fluoresce separately in a second energy band. An excitation path directs x-rays toward the sample; a first detection path detects x-ray fluorescence of the first energy band from the sample; and a second detection path detects x-ray fluorescence of the second energy band from the sample. The level of arsenic can be obtained by analyzing the x-ray fluorescence from both detection paths, and using a constant, e. g., the intensity ratio of PbL α1, to PbL β1 , which relates the level of lead in the second energy band to the level of lead in the first energy band. The excitation path and each detection path may each include a monochromating optic to transmit the desired x-ray energy band, e.g., a doubly curved optic.

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： 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.
