Production of ¹¹¹In from an In/In₂O₃ target

A method was developed to produce ¹¹¹In from an In/In₂O₃ target, whereby the parent ¹¹¹Sn was separated from the target material by means of ion exchange, using AG1-X4 and AG MP-1 anion exchange resins. The chemical separation had to be performed as quickly as possible, to ensure the highest possible yield of the final product ( ¹¹¹Sn has a half-life of 35.3 minutes). The ¹¹¹Sn is left on the resin to decay to ¹¹¹In, which is then eluted from the column. This method ensures that impurities in the final product are kept to a minimum.
