    摘要： A technique for analyzing fluids by means of x-ray fluorescence applicable to any fluid, including liquids and gases, which emit x-ray fluorescence when exposed to x-rays. The apparatus includes an x-ray source (82) including an x-ray tube (64) having improved heat dissipating properties due to a thermally-conductive, dielectric material (70, 1150). The x-ray tube also includes means for aligning (100, 2150, 2715) the tube with the source housing whereby the orientation of the x-ray beam produced by the source can be optimized, and stabilized over various operating conditions. The method and apparatus may also include an x-ray detector having a small-area, for example, a PIN-diode type semiconductor x-ray detector (120), that can provide effective x-ray detection at room temperature. One aspect of the disclosed invention is most amenable to the analysis of sulfur in petroleum-based fuels.

    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.

    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.
