This section describes how you set the solvent composition for the quaternary pump (solvents A to D). The steps and examples apply equally to the ternary pumps of the dual pump (solvents AR to CR and AL to CL).
Follow these steps
In the Instrument Configuration Manager, in the dialog box for the pump, check and the change the following if required:
Number of the solvents to be used with the pump
Standard solvent names
These solvent names appear in the Chromeleon user interface.
In the Chromeleon Client, determine the percentage of solvent that you want to deliver.
Set the percentage for solvents B, C, and D (%B, %C, %D). Solvent A (%A) automatically delivers the remaining volume.
Examples
To deliver 100% of solvent %A:
Set %B, %C, and %D to 0%.
To deliver 100% of solvent %B (or %C or %D):
Set %B (or %C or %D) to 100%. The remaining solvents are automatically set to 0%.
To deliver 20% of solvent %A, 40% of solvent %B, 30% of solvent %C, and 10% of solvent %D:
Set %B to 40%, set %C to 30%, and set %D to 10%. %A is automatically set to 20%.
