Pump Operating Parameters
Refill Time
Refill time is the duration of the piston
return stroke.
The refill time can be adjusted from
125–1000 ms.
Normally, you can use the default value
of 125 ms. If cavitation occurs, then use
a higher value.
For volatile and non-degassed solvents,
better performance may be achieved
by entering a higher value, up to the
limits shown.
Inlet Pressure
Inlet pressure is the pressure at the inlet
to the pump head.
The inlet pressure can be adjusted from 0–50 MPa.
Compressibility
Compressibility is a compensation parameter for solvent compressibility.
The compressibility can be adjusted from 0–2000 Mbar
-1
. The standard compressibility values
are 34 for water, 162 for methanol, and 180 for acetonitrile.
