If you are using the vacuum degasser for the first time, if the vacuum degasser
was switched off for any length of time (for example, overnight), or if the
vacuum degasser lines are empty, you should prime the vacuum degasser
before running an analysis.
The vacuum degasser can be primed either by drawing solvent through the
degasser with a syringe or by pumping with the quaternary pump.
Priming the degasser with a syringe is recommended, when:
• vacuum degasser is used for the first time, or vacuum tubes are empty, or
• changing to solvents that are immiscible with the solvent currently in the

is recommended, when:
• quaternary pump was turned off for a length of time (for example, during
• solvents have been changed.
