Chemical and physical parameters affecting the performance of the Os-191/Ir-191m generator

Journal Article · · ACS Symp. Ser.; (United States)
The development of an Os-191/Ir-191m generator suitable for radionuclide angiography in humans has elicited much interest. This generator employs (OsO/sub 2/Cl/sub 4/)/sup 2 -/ on AG MP-1 anion exchange resin with a Dowex-2 scavenger column and is elute with normal saline at pH 1. The parent Os species is, however, neither well-defined nor homogeneous leading to less than optimal breakthrough of Os-191 (5 x 10/sup -3/%) and modest Ir-191m yield (10-15%). The effect of a range of parameters on generator performance has been evaluated as has been the way in which the assembly and loading process affects generator performance. In addition, a number of potential alternative generator systems have been evaluated. 11 references, 2 figures, 8 tables.
