A simple, one page guide to storing polarographic and optical dissolved oxygen sensors.

Yes, in a closed system, gas phase temperature is directly proportional to pressure and therefore measured oxygen content. In solution, temperature is inversely proportional to dissolved oxygen content.

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.

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.
