ABSTRACT:
An apparatus for the quantitative in-line X-ray fluorescence analysis of rries by means of a radioactive preparation, e.g. Cd-109, and an X-ray fluorescence detector. The apparatus comprises a substantially vertical measuring tube with inlet and outlet for the slurries to be investigated, and a measuring station. Above the measuring station which contains the radioactive preparations and the fluorescence detector there is provided a filling level control which controls the state of opening of the outlet.
