Gauge corrections parameters

There are two main corrections which have to be made to observed parameters in both static and flow systems. First, if the pressure gauge is at a temperature different from that of the reaction vessel, allowance must be made for thermal transpiration 14). Second, if a heated filament is in a steady state, there will be a temperature gradient at the ends where it is attached to heavier gauge supports, and, especially for short filaments, the necessary correction (25) can be quite large. 

With the fitted parameters available at two temperatures, predictions at intermediate temperatures can be obtained to gauge the ability of the BFCM to correctly predict the temperature dependence of conductivity. Comparisons are made with Sone s data at 45°C. One problem in attempting this is lack of reliable sorption isotherm data at temperatures near 45°C. This was remedied by implementing the chemical model of Weber and Newman developed for determining X for a vapour-equilibrated membrane [55] and using it to provide sorption isotherm data. A standard error of 0.038 was used on the activity (the same standard error as was used at 30°C) to provide error bars within which conductivity is expected to lie.
