title: Extending the life of a 99Tcm generator: a simple and convenient method for concentrating generator eluate for clinical use.
abstract: 99Tcm-pertechnetate can conveniently be concentrated 5-20-fold by passing up to 20 ml through a sequence of two (or three) disposable columns, one (or two) to remove chloride and one to concentrate the pertechnetate for subsequent elution with a small volume of saline. This procedure is useful for utilizing eluates with low radioactive concentration in applications that require high radioactive concentration.
