A new68Ge/68Ga generator using CeO2 as absorbent for68Ge has been developed. Sharp elution curves were obtained by using 0.02 mol/l HCl as eluent. About 56% of68Ga formed on the column was concentrated in 0.5 ml of eluate. Neither radioactive impurities, nor dissolved cerium were found in the eluate.
