4.4 Exit Gas Analysis
In order to allow the user to draw conclusions regarding the status
of the culture while the bioprocess is still underway, the CO
2
and
O
2
measurements are often taken and analysed in the exit gas flow
of the bioreactor.
4.4.1 Measuring Systems (Gas Sensors)
The following measuring systems are available for exit gas analy-
sis:
INFORS HT Gas Analyser: gas analysis equipment (combined
CO
2
and O
2
sensor) from the equipment manufacturer.
Gas sensors from the manufacturer BlueSens: combined CO
2
and O
2
sensors of the type BlueInOne Ferm, BlueInOne Cell
or BlueVary

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.
4.4.2 Connecting the Gas Sensors
In order to view measurements on the operating panel, the meas-
uring system for exit gas analysis must be connected to the biore-
actor.
