Parameter Description
Solvent composition In the dialog box for the pump in the Chromeleon 7
Instrument Configuration Manager (Chromeleon 6.8
Server Configuration), set the number of the solvents
to be used with the pump. You can change the
standard solvent names (
%A1, %A2, %A3, %B1, %B2,
%B3 ) as required. The solvent names appear in the
Chromeleon user interface.
In the Chromeleon Client, set the solvent composition.
For each of the two channels, select the solvent and
percentage of solvent that you want to deliver.
• For channel A, select the solvent by setting
%A_Selector to %A1 or %A2 or %A3 . For channel B,
set
%B_Selector
to
%B1
or
%B2
or
%B3
.
•
Determine the percentage of solvent that you want
to deliver by setting the percentage for solvent B
(
%B ). Solvent A automatically delivers the remaining
volume.
Examples
:
• To deliver 100% of solvent B2, select %B2 and set %B
to 100%.
•
To deliver 100% of solvent A3, select %A3 and set %B
to 0%.
• To deliver 30% of solvent A1 and 70% of solvent B3,
select
%A1 and %B3 and set %B to 70%.
Solvent consumption You can monitor the solvent consumption when you
have entered the following information for the related
solvent:
•
Volume of solvent in the reservoir (at the beginning
of a sequence)
•
Lower limit for the solvent in the reservoir, which is
the minimum volume of liquid that must be available
in the reservoir
The
Remain Time property for the solvent reports
the time left until the liquid level is expected to reach
the lower limit. The Chromeleon software calculates
the time from the current flow rate and volume
entered.
• Warning limit when you want to be informed about
the liquid level in the reservoir
When the liquid in the reservoir reaches the lower
limit, the Chromeleon software stops the pump as
specified in the Emergency Method (or Program) if
available or aborts the queue (or batch) and stops the
pump flow.
