3.3.1 Daily Maintenance
•
Wipe up all spills immediately, especially spills of corrosive liquids.
•
Inspect the syringe pump for leaks, and correct any problems.
•
Flush the syringe pump thoroughly with distilled or deionized water
after each use and when the pump is not in use.
NOTE Do not allow the syringe pump to run dry for
more than a few cycles.
•
Check for air bubbles in the syringe(s) and tubing and remove any
bubbles that appear (see
Section B.3.17 ).
•
Replace the rinse fluid. Dionex recommends using ASTM Type I (or
better) filtered, deionized water as the rinse fluid.
•
To ensure correct drainage, the end of the waste line should not be
submerged in waste liquid. Check the volume of liquid in the waste
container and empty when needed.
Neutralize acidic and caustic wastes before disposal. Dispose of all
wastes in accordance with local regulations.
