ELECTROCHEMICAL SENSOR

摘要

An electrochemical sensor for measuring an analyte in a fluid, the electrochemical sensor having a first working electrode that includes a redox species sensitive to the analyte to be measured and a second working electrode made from a conducting substrate absent the redox species. The electrochemical sensor being capable of operation so that electrochemical effects of active contaminants in the fluid can be removed/attenuated from electrochemical signals produced by the reduction/oxidation of the redox species in the presence of the analyte.
