2124561 9310887 PCTABS00022 A process of using reverse osmosis membrane as an alternative or substitute method for the purification of a crude diagnostic agent. Crude ioversol can be purified by drawing ioversol in a process tank (12), and pumping it into a housing cartridge (16) containing a reverse osmosis membrane (18), which allows the passage of aqueous solution of low molecular weight impurities, and retain larger molecular weight molecules of ioversol which are returned to the process tank (12).
