New Ge-68 Breakthrough Test for Ge-68/Ga-68 Generators

Ga-68 for PET imaging is now available in a generator form from Eckert and Ziegler. As with all generators, there is always a possibility of some of the radionuclide held on the column (Ge-68) breaking through into the eluate (Ga-68) needed for imaging. A breakthrough test is needed with a limit of 0.001% or less of the Ge-68 parent in the Ga-68 eluate.  We have recently developed an inexpensive test using high resolution gamma spectroscopy.
