Priming the Pump
If the system has been run dry or air has diffused into the pump it might
require additional steps to get rid of the air again. Following the procedure
below will give the best and fastest results.
1 Change solvent to isopropanol on both channels.
2 Turn on the Prime function.
3 Purge the system with 10 ml, composition 50/50 and for 10 min.
4 Attach a column suitable for isopropanol and set the Max. pressure limit to
the limit of the column.
5 Run the system at composition 50/50 and a flow rate that gives a pressure
close to the limit of the column.
6 Observe the pressure fluctuations. The system is air free as soon as the
pressure is stable.
7 Change solvents and column according to the analytical conditions and
purge the system to change solvents.
