Frequency What you should do...
Daily Regularly check the volume in the waste container for the drain and
seal-washing liquids and empty the container as needed. Check the
volume of the liquid in the waste container and empty as needed.
When buffer solutions are used, flush the system thoroughly after use.
Use a solvent that does not contain buffers or salts.
Regularly
Fill the liquid reservoir of the rear seal wash system, by using fresh
liquid. Observe the precautions for the composition of the seal-
washing liquid on page 84.
Inspect the tubing for possible damage, such as cracks, nicks, cuts, or
blockage.
When buffer solutions are used, you should inspect the pump for
leakage at least once a month (

page 134).
Check the filter frits in the solvent lines for permeability. Replace the
filter frits in regular intervals when using aqueous solvents.
This is especially important with aqueous solvents. Aqueous solvents
may contaminate the filters with algae and other microorganisms that
deposit on the filter frits. Therefore, also replace the solvents at
regular intervals. Rinse the reservoirs thoroughly before refilling
them.
Check the drain line connected to the drain port at the bottom right of
the pump. 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.
Inspect the detector of the rear seal wash system for contamination.
Clean the detector if necessary (

page 127).
Depending on the pump type, check the permeability of the static
mixer (

page 148) or inline filter (

page 152).
This check is especially important when you use normal-phase piston
seals in SD pumps.
To avoid contamination of the degasser, you should prepare fresh
solvents, clean the solvent lines, and rinse the degassing channels at
regular intervals (

page 157).
Annually Recommended
Have Dionex Service perform preventive maintenance on the pump
once a year.
