TECHNETIUM-99M GENERATOR SYSTEM

摘要

A 99Mo/99mTc generator system includes a sorbent column (11) loaded with a composition containing 99Mo. The sorbent column (11) has an effluent end (31) in fluid communication with an anion-exchange column (15) for concentrating 99mTc eluted from the sorbent column (11). A method of preparing a concentrated solution of 99mTc includes the general steps of a) providing a sorbent column (11) loaded with a composition containing 99Mo, the sorbent column having an effluent end (31) in fluid communication with an anionexchange column (15); b) eluting the sorbent column (11) with a salt solution to elute 99mTc from the sorbent and to trap and concentrate the eluted 99mTc on the anion-exchange column; and c) eluting the concentrated 99mTc from the anion-exchange column with a solution comprising a reductive complexing agent.
