Cover Story: Cyclotron-produced radiometals must be separated from the irradiated target and purified from other metal impurities. We compared different methods to determine the amount of transition metals in radioactive samples. Besides commercially available colorimetric tests, PAR and XO were used as nonselective metal reagents, forming water-soluble chelates with most of the transition metals immediately. We compared the applicability of pre- and postcolumn derivatization, as well as colorimetric determination without separation. The studied methods are not suitable to completely replace atomic spectroscopic techniques for the determination of metal contaminants, but they may play an important role in the development of purification methods for radiometals and in their routine quality control.
