Abstract
The present invention relates to a column chromatographic method of manufacturing non-carrier-added high-purityLu compounds for medicinal purposes. In the method in accordance with the invention a cation exchanger and a suitable chelating agent are used. With the method in accordance with the invention it is possible for the first time to provide non-carrier-added high-purityLu compounds in milligram amounts for pharmaceutical-medicinal purposes fromYb compounds irradiated with thermal neutrons, the radionuclidesLu andYb being present in an approximate mass ratio of 1:10to 1:10for purification.
