Inability to autozero the signal
Liquid in the gas exhaust
Page 168
Possible Cause
Autozero on a peak or
void signal
Autozero on a very noisy
signal
Possible Cause
Flooding inside the
detector (pump flow
turned on while no gas
flow present)
Remedial Action
The Autozero occurred on a relatively flat section of the
chromatogram.
Reduce the noise or increase the current range.
Remedial Action
Flooding can occur if the detector is turned off while liquid is still
flowing into the detector.
See Resolving Flooding In the Detector
Charged Aerosol Detectors (VH-D20, VF-D20)
