WebIn typical microalgae cultures, pH measurement is carried out using potentiometric measuring methods with glass electrodes. Dissolved CO 2 is measured by Severinghaus principle based on potentiometric concept, with pH electrodes that are modified with a carbon dioxide permeable membrane such as polytetrafluoroethylene or silicon (Zafar et … Web21 Mar 2024 · The InPro 5000i utilizes the Severinghaus principle for measuring dCO2 in media, the same technology as a typical offline blood-gas analyzer. This introduces the opportunity to take an already proven technology from a slow manual process on the bench to a fast and easy in situ measurement.
