摘要
A method and apparatus for measuring the content of an element by means of X-ray-radiation. Electrons from the cathode of a low-power X-ray tube are directed onto one side of the anode of said tube, said anode comprising a thin layer of anode material on a beryllium plate. The electrons excite primary X-ray-radiation in the anode material, including the characteristic X-ray lines. The radiation passes out through the opposite side of the anode as transmission radiation and is directed onto the element to be measured, whereupon fluorescense occurs, said fluorescense being caused by the characteristic lines. The fluorescense lines of the substance are then isolated by means of a balanced filter.
