ABSTRACT:
The invention provides a method and apparatus for preparing aqueous solutions of technetium-99m pertechnetate. In a preferred embodiment, the eluate from a technetium-99m generator is contacted with a cation-exchange resin having adsorbed thereon a cation which forms an insoluble salt with the anion of the generator eluate, whereby there is obtained an aqueous solution of the pertechnetate in water. The solution may be concentrated by adsorption of the pertechnetate on alumina, followed by desorption using a smaller volume of aqueous electrolyte.
