The compressibility of the mobile phase has an effect on the performance of the pump. For best flow accuracy and mixing performance, you can set the parameter according to the mobile phase being used.
This check box allows you to use methods that have been developed for the G1312A/C binary pumps with the G1312B, G4220A/B, G4302A, G4782A, G7112B, G7120A and G7132A binary pumps without loss of performance.
When the check box is selected, the compressibility fields are not displayed, and the enhanced compressibility calibration is enabled. Select the required calibrated solvents from the drop-down lists using the combo boxes in the Solvents section.
Clear the check box to display the compressibility fields, which allow you to enter compressibility values as in Compressibility.
