Performance of PZC-Mo generator and labeling results prepared with its eluate and MDP kit

This paper described the performance of Tc-99m generator prepared with Mo adsorbent PZC and irradiated nature MoO3, and the labeling results of MDP kit prepared with Tc-99m eluted from PZC-Mo generator and MDP was report as well. ThreeTc-99m generators was prepared with different batches of PZC and reactor irradiated nature Mo. The adsorption efficiency of two batches of the PZC is good (96.4% and 93.4%) and that of one batch of PZC is not satisfy (77.8%). The elution efficiency is not so high, and it increases along with the elution date. The elution file is very broad till to 30 ml and the Mo breakthrough is high to unacceptable. The labelling efficiency of MDP kit, prepared with Tc-99m eluate eluted with saline containing 0.05% NaClO from Mo-PZC generator, is approximately 77∼84% and it can reach to >98% labelling with eluate without containing 0.05%HClO in eluate.
