Abstract
A system for analyzing radiochemical purity of an eluate produced from a generator is provided. The system has an elution detector made of a shielding metal. The elution detector houses a flow path template for flow of an eluate solution and an elutable isotope contained in the generator, and a monitoring device for simultaneously monitoring the generator and the eluate exiting the generator. The generator is a Technetium-99m (Tc-99m) generator, and the elutable isotope may be contained in a packed bed of a column in the Tc-99m generator. A method for analyzing radiochemical purity of eluate produced from a Technetium-99m (Tc-99m) generator or column is also provided.
