Routine And Preventive Maintenance - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

UltiMate 3000 Series:
VWD-3100 and VWD-3400RS Variable Wavelength Detectors

5.8 Routine and Preventive Maintenance

The detector is made of high-quality components and materials to minimize maintenance
requirements. All surfaces are resistant to weak acids, alkali, and organic solvents.
Nevertheless, immediately wipe up all liquids spilled onto the detector surface, by using
lint-free cloth or paper. If surfaces are exposed for longer periods, these liquids can cause
damage.
Perform the maintenance procedures listed in the table at regular intervals to ensure optimum
performance and maximum uptime of the detector. The exact maintenance schedule for the
detector will depend on a number of factors.

Regularly
Annually
Tip: Chromeleon supports functions for estimating the lifetime of consumables
and diagnostic tests to check the performance of certain detector
components (→ pages 89 and 90).

What you should do...
Inspect the fluid connections for indications of leakage or
restrictions.
When buffer solutions are used, flush the system thoroughly after
use. Use a solvent that does not contain buffers or salts
Check the drain tube connected to the drain port on the bottom right
of the detector (→ page 51). Verify that the tubing is unclogged and
is routed below the drain port. Check the volume of the liquid in the
waste container and empty as needed.
Monitor the lamp intensity (→ page 79). Replace the lamps as
necessary (→ page 119).
Have a service representative check the detector once a year to
prevent contamination and excessive wear.
