Installing the Pump
3
Priming the System
1 Open the purge valve of the pump
2 Set the flow rate to 5 mL/min.
3 Select channel A.
4 Turn the flow on
5 Observe if the solvent in the tubing of channel A is advancing towards the
pump. If not, disconnect the solvent tubing from the MCGV, attach a syringe
with a syringe adapter and pull the liquid through the degasser. Reattach
the tubing to the MCGV.
6 Pump 30 mL isopropanol to remove residual air bubbles.
7 Switch to the next solvent channel and repeat steps 5 and 6 until all
channels have been purged.
8 Turn the flow off and close the purge valve.
When priming the vacuum degasser with a syringe, the solvent is drawn through the
degasser tubes very quickly. The solvent at the degasser outlet will therefore not be fully
degassed. Pump for approximately 10 minutes at your desired flow rate before starting an
analysis. This will allow the vacuum degasser to properly degas the solvent in the degasser
tubes.
