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.
Claims7
A Ge-68/Ga-68 nuclide generator structure comprising first washing bottle containing sodium citrate solution, second washing bottle containing hydrogen chloride solution, an organic resin absorbing column connected with the first washing bottle, an inorganic resin absorbing column connected with the second washing bottle, a silica-gel cartridge connected with first pair of valves, of which one is connected to the second washing bottle and the other is connected to the organic resin absorbing column, respectively, and sodium citrate stock connected with second pair of valves, of which one is connected to the first washing bottle and the other is connected to the inorganic resin absorbin column, respectively, for producing two chemical forms of radioisotope solution Ga-68 gallium citrate and Ga-68 gallium chloride.
