The Sample plug is preceded by an optional Pre-sample Sandwich Plug, and
followed by an optional Post-sample Sandwich Plug. These are followed by an
optional three-part Post-sample Plug and Positioning Plug. In Preparative
operating mode, all of these plugs use the same solvent. In Analytical operation
mode, the Pre-sample and Post-sample Sandwich Plugs use the same kind of
solvent, but different from the loop solvent. The Post-sample Plug and Positioning
Plug use a different solvent from both the two Sandwich Plugs and the Loop
Solvent (the current solvent composition from the method). All volumes except
the Sample injection volume, Sandwich Plugs and Post-sample Plug are fixed.
Specify the volumes of the Pre-sample Sandwich Plug and Post-sample Sandwich
Plug in the adjacent fields. Click the down-arrow and specify the location of the
solvent for the Sandwich Plugs from the drop-down list; you can select from
Location, Current Container, Sample+ and Location+. Add a comment in the
Comment column, if necessary. The Comment is limited to 20 characters;
