For increased flexibility, the pump is shipped with two 3-port solvent
selectors. They allow forming binary gradients from three solvents per
channel. The solvent to be used for each channel is selected in the user
interface.
1. 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.
2. In the Chromeleon Client, set the solvent composition. For each of
the two channels, select the solvent and set the percentage of
solvent that you want to deliver.
1. For channel A, set %A_Selector to %A1 or %A2 or %A3.
2. For channel B, set %B_Selector to %B1 or %B2 or %B3.
Set the percentage for solvent B (%B). Solvent A automatically delivers
the remaining volume.
• To deliver 100% of solvent B2:
Set %B_Selector to %B2 and set %B to 100%.
• To deliver 100% of solvent A3:
Set %A_Selector to %A3 and set %B to 0%.
• To deliver 30% of solvent A1 and 70% of solvent B3:
Set %A_Selector to %A1 and %B_Selector to %B3, and set %B to
70%.
