Dissolved Oxygen Sensors
Welche Vorteile bietet die Online-Sauerstoffmessung?
In biologischen Prozessen wie Fermentationen und Zellkulturen ist gelöster Sauerstoff entscheidend für das richtige Zellwachstum. Und in industriellen Prozessen, in denen Korrosion eine große Rolle spielt, muss die Sauerstoffmenge oft begrenzt werden. Die Online-Sauerstoffmessung ermöglicht die Regelung des gelösten Sauerstoffs auf einen vordefinierten Sollwert in Echtzeit. Sie ermöglicht es auch, Leckagen zu erkennen, wenn durch Undichtigkeiten Sauerstoff einströmt.

Does salinity impact my DO measurement?
Yes, salinity of a solution generally has an inverse relationship to the dissolved oxygen content within the solution. Arc sensors can have the salinity value of the liquid added in to correct the measurement by using ArcAir. -
Does carbon dioxide sparging impact my DO measurement?
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. -
When should I calibrate my DO sensor?
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.

Atmospheric Pressure and Its Effects on Calibration
Hamilton dissolved oxygen and carbon dioxide sensors use measurement technology based on partial pressure. This article looks at potential sources of error that could occur during calibration if pressure is not considered.
