Operating Information
5.3 Troubleshooting
5.3.1 Faults or Malfunctions from
Moisture in the Exhaust Air
Humidity, e .g . condensation in the exhaust line,
can damage the sensors in the BioPAT
®
Xgas or
disrupt the exhaust measurement!
In the event of moist exhaust air that is warmer
than the ambient air, condensation can form in
the exhaust line and be forced into the module.
Check the exhaust line regularly for any conden-
sation that may have formed.
t
Allow the condensation to drain off and dry
the BioPAT
®
Xgas with compressed air. You do
not need to interrupt the measurement. In
doing so, note that the device is now
determining the gas concentrations in the air
being pumped through.
System interruptions on Biostat
®
B or B-DCU II
t
Disconnect the tubing from the inlet to the
BioPAT
®
Xgas. Allow the condensation to drain
off, e.g. into a vessel or down the lab drain.
t
Connect clean, dry compressed air and flush
the BioPAT
®
Xgas.
t
Reconnect the exhaust air segment tubing to
the BioPAT
®
Xgas.
t
If larger amounts of condensation occur, and
you continually have to dry the BioPAT
®
Xgas,
you can channel the exhaust air through a
condensation trap [→ Information on request].
