摘要： A method is described for obtaining purified 68Ga. The method comprises eluting 68Ga from a sorbent in and/or on which are sorbed 68Ga and 68Ge, so as to generate a crude 68Ga solution. The sorbent should have a higher affinity for 68Ge than for 68Ga. The crude 68Ga solution is then applied to a medium cation exchange resin, and the resin is eluted with an aqueous alcohol so as to retain the 68Ga on the resin and remove unwanted species from the resin. The resin is then eluted with an eluent, which may be an acidic solution, an alkaline solution or a solution of a species capable of complexing 68Ga ions, so as to obtain an eluate comprising purified 68Ga ions.

摘要： A sorbent for sorbing radioactive ions is described. The sorbent comprises a porous crystalline powder of a metal oxide or mixed metal oxide. A process for making the sorbent comprises the steps of reacting a metal halide or a mixture of metal halides and an alcohol to form a gel; heating the gel to form a particulate material; exposing the particulate material to an oxidant to form a powder; and heating the powder to a temperature sufficient to at least partially melt or sinter particles of the powder so as to form the sorbent.

摘要： An alternating flow column chromatography apparatus comprising a ‘U’ shaped or T shaped separation column including at least one loading port for loading of components for separation, a first purification column in fluid communication with one end of the separation column and a second purification column in fluid communication with another end of the separation column, at least one eluent input port, an eluate output port and an alternating flow valve in fluid communication with the primary eluent input port, the eluate output port, the first purification column and the second purification column wherein, when operated, the alternating flow valve reverses the flow of eluent through the purification columns and the separation column. Also a method of using the apparatus. A benefit of the apparatus and method is more efficient operation compared to existing direct flow column chromatography apparatuses.
