Using the Module
Setting up the Pump with the Instrument Control Interface
Timetable Settings
Use the Timetable to program changes in the pump parameters during the
analysis by entering a time in the Time field and appropriate values in the
following fields of the timetable. Changes in flow rate occur linearly from
either time zero or the time of the last defined change; other parameters
change instantaneously at the time defined in the timetable.
Show Advanced Timetable toggles the timetable display between standard mode
and advanced mode.
The following parameters can be changed:
• Change Contacts
• Change Flow
• Change Max. Pressure Limit
• Change Solvent Composition - You can only use solvents, which have been
• Function centric view - This checkbox allows you displaying parameter
Blend Assist
The Blend Assist table allows you to blend two or more solvents or solvent
mixtures from stock solutions. The blends must be of pure solvents or pure
solvents with additives. For example, you can blend 100 % water with 10 %
isopropanol in water.
• Channel: The channel name.
• Type: The type of solvent
• Calibration: Click the down arrow and select the solvent or solvent mixture
• Name: Enter a name for the solvent or solvent mixture in this field.
• Stock conc.: For solvent mixtures, specify the concentration of the additive
• Final conc.: Enter the concentration of the additive that you want to achieve

in this field. The pure solvent and solvent mixture will be blended to
achieve the Final conc. For the relationship of stock concentration and
concentration in the mixture, the composition accuracy needs to be
considered (see "Performance Specifications" on page 30).
