5 Optimizing Performance
Using Solvent Calibration Tables
Using Solvent Calibration Tables
Agilent Solvent Calibration Tables provide an algorithm for the pump to
automatically determine the correct compressibility associated with the current
system pressure.
Solvent definition tables for most common solvents are now available for
download.

How it Works
The compressibility of the mobile phase has an effect on the performance of the
pump. For best flow accuracy and mixing performance, the compressibility
parameter in the Method Settings of the pump shall be chosen according to the
mobile phase being used. This method setting activates the algorithm
associated with the Agilent Solvent Calibration Tables.
If your solvent is neither available in the user interface nor in the library, please
use generic solvents. "Generic aqueous" gives good results for most solvent
mixtures with at least 50 % water, which have similar properties as pure water.
For other solvents with high organic percentage, "Generic organic" gives a good
approximation.
