Influence of the Generator in-Growth Time on the Final Radiochemical Purity and Stability of Radiopharmaceuticals
pH, 99Mo, 103Ru, and 131I amounts and radiochemical purities (mean ± standard deviation) of the evaluated generators’ elutions.
Type of generator
Type of elution
E.P.: European pharmacopoeia; 36, 48, and 72 h indicate the time from the previous elution; the amount of 99Mo represents the % of total radioactivity in the generators’ eluates determined with “rapid method”; 103Ru (0.497 MeV) and 131I (0.365 MeV) are the most common gamma radionuclide detectable by gamma spectrometry, and in the table are reported the % of total radioactivity in the generators’ eluates.
