NUMERICAL−SIMULATION OF THE TIME−DEPENDENT CURRENT TO MEMBRANE−COVERED OXYGEN SENSORS .2. THE APPROACH TO THE STEADY−STATE AND THE RESPONSE TO A STEP CHANGE FOR A MICROCATHODE

Abstract:
In this paper we develop further a model for the operation of the Clark electrode that we have described previously. The difficulties of using this type of sensor with a continuously applied potential are considered, and the nature of the diffusion processes as the steady state is approached for a gas sample or a still liquid sample is investigated. The effects of step changes in gas sample partial pressure are considered, together with the resulting response time of the sensor to such a change
