Method of operating and amperometric measuring cell

摘要

The invention relates to a method for operating an amperometric measuring cell which includes at least a measuring electrode 2 and a counter electrode 3 in an electrolyte chamber 4 filled with an electrolyte. The measuring cell is closed off by a permeable membrane 7 with respect to the measurement sample to be detected. The method of the invention improves the run-in performance of the measuring cell 1. The method includes the step of applying a voltage U1 across the electrodes (2, 3) during a first time span T1 starting at a reference time T0. A reference voltage U0 is assumed at the start of the measurement and the voltage U1 is increased relative to the reference voltage U0.
