A zirconium-manganese-iron alloy, St 909, was evaluated as a purifier in tritium handling, transport, and storage applications. High efficiency removal of CH4, CO, CO2, NH3, and O2 was observed at concentrations of 0.1 to 1% in helium. Gas streams at 100 to 5000 sccm were passed through getters operated at 600–800°C. On-getter residence times of two seconds were required to achieve >99% removal of these reactive impurities. At this removal efficiency level, the individual impurity capacity of 100 g of St 909 purifier at 800°C was 0.59, 0.28, 0.19, 0.14 and 0.12 moles of CH4, CO, CO2, O2 and NH3, respectively. Hydrogen containing gasses; CH4 and NH3; were cracked on the purifier and the resultant elemental hydrogen was released. Only 8 ± 2 scc of H2 were retained on 100 g of St 909 at 800°C. These features suggest that this alloy can be employed as an efficient purifier for hydrogen isotopes in inert gas, nitrogen, or perhaps even H, D, or T streams.
