HPLC configuration for the purification of [18F]EF5 using Oasis HLB columns (4.6×20 mm) and the semi-preparative HPLC system. The crude reaction mixture was initially passed through Oasis cartridges (n=2 in series) connected in place of injection loop on the HPLC injector in “load” position (left panel). Further purification was achieved by switching the injector to “inject” position and eluting the contents onto the semi-prep column (right panel).
