✦ Synopsis

An electrical potential develops across the membrane when the moving streams in a continuous flow dialyzer module are electrolytes of different composition. The steady-state value for a pair of solutions and flow rates is little affected by introducing air bubbles into the flowing streams. The potential largely depends on the relative mobilities of the ions through the membrane, and these can be often qualitatively assessed from mobilities in water. In automated analysis of ionic metabolites, electrolyte composition of diluent and recipient stream reagents has an effect on sensitivity which can be predicted from these electrical potentials. 549
