Abstract
A system for electrochemical monitoring for the appearance of an ionic species of interest in a first flow stream by merging the first flow stream with a second flow stream containing a mixture of the ion to be sensed and a second non-interfering tag ion in a substantially fixed ratio. A pair of ion-sensing electrodes responsive, respectively, to the ionic species of interest and the tag ion are used to detect the activity of the species at a location in the merged stream. The difference between the measured potentials of the two ionic species in the merged stream is a constant ratio which is unaffected by fluctuations in the rate at which the two flow streams are mixed.
