  • Title: Quantitative online isolation of ⁶⁸Ge from ⁶⁸Ge/⁶⁸Ga generator eluates for purification and immediate quality control of breakthrough.
    Author: Eppard E, Loktionova NS, Rösch F.
    Journal: Appl Radiat Isot; 2013 Dec; 82():45-8. PubMed ID: 23948310.
    Abstract:
    The breakthrough of ⁶⁸Ge from a ⁶⁸Ge/⁶⁸Ga-generator is one of the most sensitive parameters in the context of the clinical application of ⁶⁸Ga-radiopharmaceuticals. The difficulty in its determination lies in the "spectroscopic invisibility" of ⁶⁸Ge within an excess of ⁶⁸Ga. The introduced method for determining the ⁶⁸Ge content of the ⁶⁸Ge/⁶⁸Ga-generator eluate involves the quantitative separation of ⁶⁸Ga from ⁶⁸Ge, using a cation-exchanger. The eluate contains ⁶⁸Ga free of ⁶⁸Ge, which can be determined immediately, i.e. prior to the application of the ⁶⁸Ga-radiopharmaceutical.
