However, the conventional approach is not suitable for automation of the isolation process. Improvement of the distillation system was there performed in this study by introducing a water trap for the recovery of Br-76 instead of the thermal chromatography technique. Prior to the isolation studies, isotopically enriched copper selenide, a target material for Br-76 production, was prepared. X-ray diffraction spectroscopy showed that copper selenide was successfully formed by heating the mixture of Cu and Se-76 under sufficiently high vacuum condition. Isolation studies using cost-effectively producible Br-77 demonstrated that reasonable recovery efficiency (66.5 ± 5.3%) was achieved by the new distillation system. Large-scale isolation studies showed that subGBq to GBq order of Br-76 was successfully recovered under the optimization condition. Since the isolated radiobromine had high radionuclide purity, these results strongly suggested that enough radioactivity of highly pure Br-76 to provide several patients will be recovered by using the improved system, more suitable for the future automation of its isolating process.
