|POSSIBLE CAUSE||REMEDIAL ACTION|
|Contamination (Typically injector or column)||Flush the system using an appropriate solvent.|
|Improper reference wavelength||The sample must not absorb in the range of the reference wavelength. Consider using a method without reference wavelength.|
|Selected bandwidth too high||Select a lower bandwidth.|
|Degassing channels contaminated||Purge the pump (all channels) to rinse the degassing channels (refer to Pump Operating Manual).|
