Solvent and Waste Liquid Parameters
Parameter Description
Solvent composition In the dialog box for the pump in the Instrument
Configuration Manager, set the number of the
solvents to be used with the pump. You can change
the standard solvent names as required. The solvent
names appear in the Chromeleon user interface.
In the Chromeleon Client, set the solvent composition.
For more information, see the related section in
Pump-Specific Information ( } page 215) .
Solvent consumption You can monitor the liquid level in the solvent
reservoir (solvent consumption) when you have
entered the required information for the related
solvent. Based on this information, the Chromeleon
software
calculates the liquid level. To monitor the
liquid level in real time, based on real physical
measurement, install the Vanquish Solvent Monitor.
The solvent monitor is available as an option (see
Optional Accessories ( } page 269) ).
For monitoring from the Chromeleon software, enter
the following information:
• 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 Instrument Method if
available or aborts the Queue and stops the pump
flow.
Relevant for dual pump only
You can monitor the solvent consumption of the dual
pump as a whole if the two pumps share the same set
of solvent reservoirs. If the pumps are connected to
different sets of solvent reservoirs, you can monitor
the solvent consumption separately each pump (see
Monitoring the Solvent Consumption ( } page 226) ).
