Abstract
In this paper we describe test methods useful to evaluate the performance of Ge/ Ga generators and to assess radionuclidic purity of the eluates. In our tests on the elution profile of the generator, we found that less than 8.0 ml are sufficient to recover > 98 % of the activity. Elution yield was conforming the manufacturer specifications, being initially > 85 % and still > 64 % after 7 months of use. 68Ge breakthrough in the eluates was limited; even if radionuclidic purity was > 99.99 % , further analyses, in addition to physical tests, is recommended in order to assess chemical impurities that could determine interferences in labelling procedures. Keywords: Ga/, Ge generator, radionuclidic purity, quality assurance
