Priming the System
Regular Priming
1 Open the purge valve of your pump by turning it counterclockwise and set
the flow rate to 5 mL/min.
2 Flush the vacuum degasser and all tubes with at least 10 mL of solvent.
3 Repeat step 1 and 2 for the other channel(s) of the pump.
4 Set the required composition and flow rate for your application and close
the purge valve.
5 Pump for approximately 10 minutes before starting your application.
When When the pumping system has been turned off for a certain time (for example, overnight) air will
rediffuse into the solvent channel between the vacuum degasser and the pump. Solvents containing
volatile ingredients will slightly lose these if left in the degasser without flow for a prolonged period
of time.
Preparations Switch the system on
NOTE
The purge tool of the LabAdvisor or Instrument Utilities can be used for automatically
purging the pump.
