In-process Measurement

Temperatures in the exhaust air >40°C or
oxygen-free exhaust air can damage the sensors
in the BioPAT Xgas!
®
The pure nitrogen used during zero-point cali-
bration of the DO sensor in the culture vessel
must not escape into the BioPAT
and condensation in the exhaust air can damage
the sensors.
Ensure that exhaust cooling is always active
t
during measurement. Monitor whether
condensation forms in the exhaust line. Abort
the measurement if condensation enters
the BioPAT Xgas. Dry the BioPAT

at the work place. If required, calibrate the
zero point of the built-in DO sensor with pure
