Operational Hints for the Vacuum Degasser
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
vacuum tubes.
Priming the vacuum degasser by using the quaternary pump at high flow rate
is recommended, when:
• quaternary pump was turned off for a length of time (for example, during
night) and volatile solvent mixtures are used, or
• solvents have been changed.
