摘要： An electrochemical sensor apparatus and electrochemical sensing method are described, using one or more working electrodes (110) of boron doped diamond (BDD). A cathodic reduction process provides a cathodic measurement and, substantially simultaneously, an anodic oxidation process provides an anodic measurement. A sum of a content of two equilibrium species within an aqueous system is obtained using both the cathodic measurement and the anodic measurement. One example measures total free chlorine by simultaneously measuring hypochlorous acid (HOCI) and hypochlorite ion (OCI-). The BDD working electrode (110) comprises at least one ablated region (115) which introduces non-diamond carbon sp
2 material. The ablated region (115) may comprise one or more grooves (114) which are cut into the working surface (112), e.g. by a laser.

摘要： An electrochemical sensor (A, A') is specific for the detection of peracetic acid in a solution which also contains hydrogen peroxide. A potential is applied between a reference electrode (120, 120') and a working electrode (118, 118'). A read voltage (fig. 7) is selectively pulsed to the working electrode and then through the solution to a counter electrode (122, 122'). The current flowing between the working electrode and the counter electrode is dependent on the peracetic acid concentration in the solution (fig. 6). By careful selection of the read voltage, the contribution of hydrogen peroxide to the current flow is virtually negligible. The sensor effectively measures peracetic acid concentrations in the range generally employed in sterilization and disinfection baths (100-3000 ppm.).

摘要： The invention relates to a method for detecting redox-active substances by combining an electrochemical measuring cell, which is covered by a membrane, with a redox mediator and a control unit. The measuring cell contains a number of working electrodes arranged in close spatial proximity and contains protective and counter electrodes. The control unit comprises a number of controllable direct voltage sources for polarizing the electrodes and a time control which controls the time sequence of the electrode polarization and of the measurement of the currents. The analyte reacts with the redox mediator in the measuring cell, whereby for very small analyte concentrations in a working mode I, a redox recycling is initiated on the working electrodes that are respectively polarized as an anode and cathode. The current flowing in this instance is amplified by the redox recycling and is proportional to the analyte concentration. In the case of higher analyte concentrations, a working mode II is realized by automatically changing the electrode polarization during which the measuring cell functions like a known amperometric sensor. The inventive method is characterized by a very low limit of determination and by a very large dynamic measuring range.
