Figure 5.
Elution profile of the 68Ge/68Ga generator and formation of 68Ga. 10 h after the former elution, there is an equilibrium of formation of 68Ga and decay to 68Zn, and the maximum of the elutable activity of 68Ga is reached. By two half-lives after the former elution, 75% of the maximum 68Ga activity is already elutable from the generator.
