In this paper, the authors demonstrate a new technique for measuring hydrogen isotope separation factors in hydrogen-absorbing metals. Using external ion beam nuclear reaction analysis of metal electrodes in an operating electrochemical cell, the authors monitor in situ the deuterium content of the electrode. changing the deuterium/hydrogen ratio in the electrolyte changes the observed deuterium content of the metal electrode, and, assuming identical ultimate total metal loading for deuterium, hydrogen, and any mixture of deuterium and hydrogen, a simple calculation yields the separation factor.
