Pj. Blower, EXTENDING THE LIFE OF A 99TCM GENERATOR - A SIMPLE AND CONVENIENT METHOD FOR CONCENTRATING GENERATOR ELUATE FOR CLINICAL USE, Nuclear medicine communications, 14(11), 1993, pp. 995-997
Tc-99m-pertechnetate can conveniently be concentrated 5-20-fold by pas
sing up to 20 ml through a sequence of two (or three) disposable colum
ns, one (or two) to remove chloride and one to concentrate the pertech
netate for subsequent elution with a small volume of saline. This proc
edure is useful for utilizing eluates with low radioactive concentrati
on in applications that require high radioactive concentration.
