Optimizing Performance
Optimize the Compressibility Compensation Setting
5 Starting with a compressibility setting of 10 × 10
-6
/bar increase the value in
steps of 10. Re-zero the integrator as required. The compressibility
compensation setting that generates the smallest pressure ripple is the
optimum value for your solvent composition.
