Use of ion chromatography and a flow-through scintillation detector was investigated for determination of {sup 14}C, {sup 55}Fe, {sup 60}Co, {sup 63}Ni, {sup 90}Sr, {sup 90}Y, {sup 99}Tc, and {sup 147}Pm. Experiments were conducted with prepackaged elution programs and samples prepared from calibrated standards. The technique produced effective separation of the radionuclides in approximately one hour. Response of the flow-through detector was linear over the full range of activities, from 2 to 1000 Bq (50 to 30,000 pCi). Detection efficiencies ranged from 9% for {sup 63}Ni to 140% for {sup 90}Y. Lower limits of detection ranged from 5 Bq (140 pCi) for {sup 90}Y to 34 Bq (910 pCi) for {sup 63}Ni.
