113Sn-113mIn generator with a glass beads column

The adsorption characteristics of 113Sn(IV) and 113mIn(III) on glass beads from NaCl solutions have been studied. On the basis of these studies, 113Sn-113mIn generator has been prepared by adsorbing 113Sn on the glass beads column. 113mIn has been eluted by the 0.16M NaCl solution with pH 3.0, remaining 113Sn adsorbed on the glass beads. The yield of 113mIn has been about 73% in the first 6 ml of eluate, while the breakthrough of 113Sn has been about 0.042%.
