The current at the downstream
detector electrode is therefore different from that at the predictor electrode as a result of the enzyme reaction and the difference of the currents,
corrected for the dimensions of the electrodes, is proportional to the concentration of sulfite. The method enables a straightforward correction
of the interfering current at the detector electrode and a determination of the analyte concentration. The effect of interferences from ascorbic
acid, ethanol, sorbic acid and tartaric acid in the detection of sulfite is efficiently removed
