Potentiometric gas‐sensing membrane electrodes have been investigated for both the CO 2 and NH 3 systems from the point of view of selectivity and dynamic response. Selectivity is found to be primarily determined by the acid‐base properties, not the volatility, of the interferents. The dynamic response characteristics, on the other hand, are a function of the internal electrolyte layer and the osmolarity of the sample solution.
