N2 - An electrochem. sensor app. and electrochem. sensing method within an aq. system are described, using one or more working electrodes of boron doped diamond (BDD). A cathodic redn. process provides a cathodic measurement and, substantially simultaneously, an anodic oxidn. process provides an anodic measurement. A sum of a content of two equil. species within the aq. system is obtained using both the cathodic measurement and the anodic measurement. One example measures total free chlorine by simultaneously measuring hypochlorous acid (HOCl) and hypochlorite ion (OCl-). [on SciFinder(R)]
