Parameter Description
Pressure limits The allowed pressure range is indicated in the dialog
box for the pump in the Chromeleon 7 Instrument
Configuration Manager (Chromeleon 6.8 Server
Configuration). You can adapt the upper and lower
pressure limits within the allowed range.
•
The lower pressure limit helps to prevent the pump
(and column) from running dry. A typical setting is
1 MPa.
• The upper pressure limit helps to protect the column
from too high pressure. The column and the
application determine the appropriate setting.
When the pump pressure is outside the specified
limits, the Chromeleon software stops the pump flow
and aborts a running queue (or batch).
Pump pressure In the dialog box for the pump in the Chromeleon 7
Instrument Configuration Manager (Chromeleon 6.8
Server Configuration), the
Pump_Pressure check box
is selected as a standard when the pump is set up in
Chromeleon. The Chromeleon software uses this
setting to generate the channel for recording the
pump pressure (which corresponds to the column
pressure).
Always record the pump pressure. If a problem occurs,
the information from the pump pressure channel can
provide helpful information to identify and eliminate
the source for the problem.
Purge Purge the pump in the following situations:
•
To remove air bubbles that might be trapped in the
system
• When changing to a different type of solvent
For details, see section 6.8 Purging the Pump, page 98 .
