Abstrakt: This study proves that the mode of transient performance in amperometric sensor can clearly indicate the excessive polarization of auxiliary electrode as a root cause of unstable signal or long transition period. These findings allow determining a dramatic decrease in the contact area of consumables auxiliary electrode (potential determining material) with its conductive skeleton that causes the sharp rise in polarization.
