Long-term shut-down of the system
• Flush system with water to remove buffer.
• Remove all samples from the sampler and store according to good
laboratory practice.

Prepare the pump
Purge
Use the Purge function to:
• fill the pump,
• exchange a solvent,
• remove air bubbles in tubes and pump heads.
Condition
Use the Conditioning function:
• daily when starting the pump,
• to minimize pressure ripple by dissolving air bubbles in pump heads.
NOTE
Condition your complete system with solvents and composition of your application (for
example 50 %/50 % A/B at 0.5 mL/min).
