Preparing the system
Purging the Pump
Purge the pump, if ...
•
The pump has been primed for the first time.
•
The pump is to be purged with fresh solvent before using the system, or
when the solvent is to be exchanged for another.
•
The pump has been idle for a few hours or more (air may have diffused into
the solvent lines and purging is recommended).
•
The solvent reservoirs are refilled, and the pump requires purging to fill the
system with fresh solvent. If different solvents are to be used, ensure that
the new solvent is miscible with the previous solvent and if necessary use
an intermediate step with a co-miscible solvent (isopropanol is often a good
choice, check with a solvent miscibility table).
