6 .2 .6 Programming
Fundamentals:
A gradient program is programmed by lining up individual segments.
Each segment is defined by
• an start concentration %B
• a end concentration %B
• one or two pump modules
• valves (if applicable)
• time limit
When solvent valves are used, the pump combinations A1/B1, A2/B1, A1/B2, A2/B2 of the eluents
can be selected.
Start and end concentrations are entered in %B. The time is entered in 00:01:02 (hh:mm:ss). The
starting and end point of the mixture ratio of Pump B (0 – 100%) can only be entered if two pump
modules are used. The increase from the start to the end concentration is linear.
