  • Gallium-68 radioisotope generator and generating method thereof
    Patent number: 8894860
    Abstract: A Gallium-68 (Ga-68) radioisotope generator includes a generating column and a citrate eluent. The generating column is at least partially filled with an ion-exchange resin with glucamine groups to absorb germanium-68 (Ge-68) and Ga-68 radioisotopes. The citrate eluent is added into the generating column to desorb the Ga-68 radioisotope and form an eluent containing the Ga-68 radioisotope in the form of Ga-68 citrate. A method for generating Ga-68 radioisotope is also disclosed.
    Type: Grant

  • Ga-68 radionuclide generator structure
    Patent number: 8802014
    Abstract: The invention is related a novel structure for Ga-68 radionuclide generator. It allows two washing solutions to pass through two Ge-68 absorbents to wash out different chemical forms of Ga-68 nuclide. The invention comprises the first method that will withdraw hydrochloric acid solution from the washing bottle and pass it through inorganic resin absorbing column to produce the radioisotope solution of Ga-68 gallium chloride, and the second method that will allow the radioisotope solution of Ga-68 gallium citrate to pass the organic resin absorbing column and then the silica-gel cartridge, and be washed by the hydrochloric acid solution to obtain the radioisotope solution of Ga-68 gallium chloride.
