    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: 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.

The methods and devices simplify the process of aligning an x-ray optic device (for example, a polycapillary x-ray optic) to an x-ray source or for measuring a focusing characteristic, for example, the focal length or beam shape, of an x-ray optic. In one aspect, the device includes a housing having a first aperture adapted for receiving an x-ray optic and a surface having an x-ray flourescent material from which visual fluorescence occurs when impinged by x-rays. The size and shape of fluorescence from the surface may be varied by moving the surface to determine, for example, the focal length of the x-ray optic.

    摘要: A measurement and processing technique enabling x-ray analysis systems to handle dynamically changing samples and other conditions resulting in both significant and insignificant measurement changes. A stream of input values related to measured compositional information of the sample is received, and a stream of output compositional values is produced. The current output value y[n] is set as a function of the received input value x[n] if the received input value x[n] differs from x[n−1] by more than an intensity-dependent deviation limit; and alternatively the current output y[n] is set as a function of the previous output y[n−1] and the received input value x[n] if the received input value x[n] differs from x[n−1] by less than the intensity-dependent deviation limit. The intensity-dependent deviation limit is maintained as a function of the intensity of the measured compositional information. Types of dynamically changing samples to which the technique is applicable include fluid streams and sheet production, monitored by, e.g., XRF and XRD systems.
