摘要： An apparatus for continuously measuring the elemental contents of a slurryndependent of the slurry density and slurry composition, by utilizing X-ray fluorescence analysis. The apparatus includes a measuring chamber with a slurry flow channel and a first measuring window disposed on one side of the channel and a second measuring window disposed on the other side of the channel. A first source of primary radiation and a target are disposed behind the second measuring window. A detector is disposed behind the first measuring window. An annular source of primary radiation is provided around an open passage formed by a collimator between the detector and the first measuring window. The collimator collimates the primary radiation and the target radiation as well as the X-ray radiation excited by the first source and the annular source.

摘要： A method and apparatus for continuous measurement, by X-ray fluorescence lysis, of the elemental content of a slurry, independently of slurry density and slurry composition. The slurry, a source of primary radiation, a target, and a detector are arranged so that the slurry passes between the source and the detector, and a portion of the primary radiation excites the elements in the slurry to emit elemental X-ray radiation. The primary radiation also excites the target, to emit target radiation which passes through the slurry. The primary, target, and elemental radiations are absorbed by the detector, and the absorbed radiations are evaluated to determine the elemental content of the slurry.
