Study of the Impurities in Sodium Fluoride[18F] Injection

This article describes the preparation process of fluoride [18F] sodium injection, the samples before and after QMA column purification, and the injection products, using a HPGe、ICP-MS、 liquid scintillation counter is used to analyze the levels of nuclide impurities, elemental impurities, and tritium, in order to determine the introduction and removal processes of various impurities during the preparation of injection solutions.
