Medical isotope generator systems are disclosed according to some aspects . In one aspect, a 90Y generator system comprises a generator column (202), a concentration column (203), and a flow control system, through which the g enerator column and the concentration column are in fluid communication. The flow control system provides a plurality of flow configurations for deliver ing a milking solution to the generator column, the concentration column, or both, and for delivering an eluent solution to the concentration column in either a forward or a reverse flow direction. The generator column can compr ise a 90Sr stock adsorbed on a sorbent. The milking solution preferentially elutes 90Y from the generator column. The concentration column comprises a s orbent that captures 90Y from the milking solution without altering the milk ing solution. The eluent solution elutes 90Y from the concentration column. |
