Maintenance Plan

Page 170
Optimum detector performance, maximum uptime of the detector, and
accurate results can be obtained only if the detector is in good condition
and properly maintained.
Perform the maintenance procedures in the table on a regular basis. The
frequency given in the table is a suggestion. The optimum frequency for
maintenance depends on several factors, such as the types and amounts
of samples and solvents used with the detector.

What you should do...
Inspect the flow connections for signs of leakage or
blockage.
When you use buffers or salt solutions, flush the detector
thoroughly after use with an appropriate solvent that does
not contain buffers or salts.
The stability of water or highly aqueous (< 5% organic
modifier) mobile phase is highly susceptible to microbial
growth. Prepare such mobile phases freshly on a daily
basis
Inspect the flow connections for damage, such as cracks,
nicks, cuts, or blockage.
Check that all warning labels are still present on the
detector and clearly legible. If they are not, contact
Thermo Fisher Scientific for replacement.
Check the drain tubes:
• Check that the drain tubes properly connect to the drain
ports on the bottom right side of the detector.
•
Make sure that the tubes are unclogged and routed
below the level of the drain ports.
•
Check the volume of the liquid in the waste container.
Empty the container as needed.
Check all electrical connections to ensure that they are
properly seated.
