“…The bridge circuit for the thermal conductivity detector used in this study is discussed in detail by Ortiz (1998) and follows the example of Yabsley and Dunlop (1975). All measurements of bridge balance resistance were made with the valves on either side of the palladium bed closed to ensure a static system.…”

The range of available data on separation factors (α) in the palladium−hydrogen/deuterium system has been extended in this study using a thermal conductivity detector. The thermal conductivity detector employed a matched pair of glass-coated bead thermistors to measure the gas-phase composition of hydrogen isotope mixtures. Separation factors (α) were measured in the β-phase, over the temperature (T) and hydrogen mole fraction (x H) ranges T = 175 K to 389 K and x H = 0.195 to 0.785, respectively. These data were correlated with temperature (T) and hydrogen mole fraction in the palladium (x H) by α = exp[−0.27 + B(x H)(1000/T)0.75] and B(x H) = 0.5155 − 0.0569x H − 0.12x H 2, where B(x H) is an empirical function relating the dependence of the separation factor on composition.
