In order to allow the user to draw conclusions regarding the status
of the culture while the bioprocess is still underway, the CO
O measurements are often taken and analysed in the exit gas flow
2
of the bioreactor.
The following measuring systems are available for exit gas analy-
sis:
INFORS HT Gas Analyser: gas analysis equipment (combined

CO and O sensor) from the equipment manufacturer.

Gas sensors from the manufacturer BlueSens: combined CO

and O sensors of the type BlueInOne Ferm, BlueInOne Cell

only suitable for use in aerobic bioprocesses
2)
suitable for use in aerobic and anaerobic bioprocesses
For details on the safety, technical data, usage and maintenance
requirements for the gas sensors, see the separate documentation
provided by the sensor manufacturer. Read this documentation
before using the gas sensor and follow the instructions contained
therein.
In order to view measurements on the operating panel, the meas-
uring system for exit gas analysis must be connected to the biore-
actor.
