Two-electrode gas analysis method for electrically sensing and controlling redox reactions

摘要: A gas analysis system includes a pair of electrodes disposed in cell containing an electrolyte through which sample unknown quantity reactant is passed. The reacts with the electrolyte, changes electrical resistance proportion to concentration gas. are part externally-powered monitoring circuit alternately senses and then generates voltage between response sensed resistance, permitting generating current flow periodically being proportional amount reacting electrolyte.
