X-RAY DETECTION APPARATUS AND X-RAY DETECTION METHOD
An X-ray generation apparatus comprising: an X-ray generating unit; a dispersive crystal whose surface is irradiated with an X-ray generated from the X-ray generating unit in order to monochromatize the X-ray; and a detecting unit that detects an X-ray generated from a sample irradiated with the X-ray monochromatized by the dispersive crystal. The dispersive crystal has a single-bent shape containing the surface that is a concave surface formed by integrating concave curve lines continuously along an axis perpendicular to a plane including the concave curve line. A direction in which a position on the surface irradiated with the X-ray generated from the X-ray generating unit moves is the direction along the axis.
Active, variable sample concentration method and apparatus for sub-ppb measurements and exemplary X-ray analysis applications thereof
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 levelmeasured 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.
Support structure and highly aligned monochromatic X-ray optics for X-ray analysis engines and analyzers
A support structure having multiple highly aligned curved x-ray optics, the support structure having multiple internal partially or fully concentric surfaces upon which said optics are mounted, thereby aligning said optics along a central optical axis thereof and therefore to a source, sample, and/or detector in combination with which the support structure is useable. The surfaces may be nested around the central optical axis; and the support structure may divided longitudinally into sections around the central optical axis by walls. At least one of the x-ray optics comprises a curved diffracting optic, for receiving a diverging x-ray beam and focusing the beam to a focal area, in one embodiment a focusing monochromating optic. In an improved embodiment, an optic comprises a single layer, plastically deformed, LiF optic.
