This study presents the production and purification of the positron emitting radionuclide 63Zn. A natural copper target was irradiated with 13.5 MeV protons, and 63Zn was purified by cation exchange chromatography using 0.05 N HCl‐85% acetone as eluent. The production yield reached 1.41 ± 0.19 GBq/μA⋅h at the end of bombardment and 169 ± 30 MBq/μA·h after purification, with more than 99.9% of radionuclidic...
Carbon-11-labeled phosgene is an important labeling precursor for PET molecular probes. Despite the usefulness of [ 11 C]phosgene, some difficulties, especially in the formation of [ 11 C]phosgene process from [ 11 C]CCl 4 , hamper its use. The present article shows a simple preparation method for [ 11 C]phosgene.[ 11 C]CCl 4 was obtained using...
