CO2 sparging will not impact the DO measurement using an optical DO sensor. CO2 can impact traditional polarographic DO sensors over time thus more frequent electrolyte replacement may be needed.

The frequency of calibration will depend upon the duration of process runs and the accuracy required for process control. In bioreactor applications calibration can be performed before sterilization; however many customers choose to calibrate after sterilization as well.

The frequency of membrane and electrolyte replacement is process specific and will vary. Routine calibration before each run can identify a high nA current at the nitrogen zero point or low nA current in air, indicating a need to replace the membrane and electrolyte.

Seit geraumer Zeit werden vielfach amperometrische durch optische Sauerstoffsensoren ersetzt. Wird ein Wechsel zu optischen Sensoren in Erwägung gezogen, müssen Ingenieure berücksichtigen, welche Auswirkungen ein Wechsel des Messprinzips auf den aktuellen Prozess hat.
