  • Patent number: 10317350
    Abstract: A sample handling apparatus/technique/method for a material analyzer, which provides active, variable concentration of a sample, using a measurement marker introduced into the sample, to measurably concentrate an analyte in a liquid (e.g., water) sample. Active, variable concentration allows otherwise lower level analytes to be concentrated in a measurable way. This enables measurements at higher (e.g., concentrated) levels, which can be extrapolated to obtain their lower, original levels based on the concentration level—measured using the introduced marker as a guide. The sample handling apparatus may be used in combination with an optic-enabled x-ray analyzer, the x-ray analyzer including an x-ray engine with an x-ray excitation path and an x-ray detection path, usable during both during the concentration and analyte measurement.

  • Patent number: 9521735
    Abstract: A handheld x-ray analyzer, having an outer shell forming an inner cavity, the outer shell having at least one aperture; an x-ray engine positioned within the cavity; and a generally planar heat sink rigidly and thermally attached to the x-ray engine, and positioned in the aperture of the outer shell thereby substantially filling the aperture while providing thermal conduction between the engine and surrounding air. An outer face of the heat sink may be substantially conformal with the outer shell along one or both sides of the analyzer, and form a substantial portion of one or both sides of the analyzer. Longitudinal fins may be placed on an outer face of the heat sink to aid in thermal conduction from the engine to the surrounding air. Thermal handling, shock/vibration isolation, and moisture barriers are provided.

  • Publication number: 20160274042
    Abstract: A sample scanning apparatus/technique/method for a material analyzer, including moving a sample cell containing a sample over a measurement focal area of the analyzer according to a scan pattern, thereby scanning the sample over the measurement focal area in the scan pattern, and exposing multiple areas of the sample to the focal area. A sample cell rotator for rotating a sample cell is provided; along with a linear motion stage. The combined rotation and linear movement results in scanning the sample over the focal area in a scan pattern, thereby exposing multiple areas of the sample to the focal area. The sample scanning apparatus may be used in combination with an optic-enabled x-ray analyzer, the x-ray analyzer including an x-ray engine with an x-ray excitation path and an x-ray detection path, wherein the x-ray excitation and/or the x-ray detection path define the sample focal area.

    Abstract: An x-ray tube includes a target on which electrons impinge to form a diverging x-ray beam. The target has a surface formed from first and second target materials, each tailored to emit a respective x-ray energy profile. A first x-ray optic may be provided for directing the beam toward the sample spot, the first x-ray optic monochromating the diverging x-ray beam to a first energy from the energy emitted by the first target material; and a second x-ray optic may be provided, for directing the beam toward the sample spot, the second x-ray optic monochromating the diverging x-ray beam to a second energy from the energy emitted by the second target material. Fluorescence from the sample spot induced by the first and second monochromated energies is used to measure the concentration of at least one element in the sample, or separately measure elements in a coating and underlying substrate.
