Exchanging a Lamp
When required If noise or drift exceeds application limits or lamp does not ignite.
Tools required Screwdriver POZI 1 PT3
Parts required Deuterium lamp G1314-60100
NOTE
If you want to use the Agilent DAD lamp instead of the VWD lamp, you have to change the
lamp settings in the VWD Configuration to lamp type 2140-0590. This ensures that the DAD
lamp’s filament heating is operated like in the DAD. The instrument specifications are
based on the VWD lamp.
WARNING
If the detector has been in use, the lamp may be hot. If so, wait five minutes for lamp
to cool down.
Preparations for this procedure:
• Turn the lamp OFF.
1 Press the release buttons and remove the front cover to
have access to the lamp area.
