Entering Settings
All pump settings can be entered in the Pump
Settings
screen. You can access
this screen by selecting the
Settings
button [

Analysis
screen and then
choosing the pump. Commonly-used settings such as flow and solvent
composition can be set directly in the
Analysis
screen. The choices available
there depend on how many other modules are installed.
Purging the Pump
By opening the purge valve you can redirect the solvent flow from the pump
out through the valve exit instead of passing through the injection valve and
column. This purging process removes any undegassed or previously used
solvent within the pumping system.
