When problems with the baseline noise, baseline drift or during
wavelength validation occur, install the diagnostic cell and use it to
identify the cause:
• If the problems disappear with the diagnostic cell
The problems are caused by the flow cell that was previously
installed or the flow path or components in the flow path before the
device.
• If the problems remain with the diagnostic cell:
The device or the UV lamp is defective.
For details on the possible causes for the problems, refer to the
System Troubleshooting section in the Vanquish System Operating
Manual.
Diagnostic cell
1. If the UV lamp is turned on

Turn off the UV lamp.
2. If a flow cell is installed: Remove the flow cell from the device.
3. If the cover is installed to the flow cell opening on the device:
a) Turn the rotating locks on the cover of the flow cell opening on
the device counterclockwise until they are in a horizontal
position.
b) Remove the cover from the flow cell opening. Keep the cover to
close the flow cell opening when no flow cell is installed in the
device.
NOTICE—Flow Cell Opening
The optical ports and the contact pad for the identification chip in the
