Hints for Successful Use of the Micro 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 by pumping solvent with the nano pump
at high flow rate (2.5 ml/min). Priming the degasser is recommended, when:
• vacuum degasser is used for the first time, or vacuum chambers are empty.
• changing to solvent that are immiscible with the solvent currently in the
• nano pump was turned OFF for a length of time (for example during night)
