Compressibility (Modular LC Prep Pump Cluster)

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.

For the G1361A prep pump, the default compressibility value is 100 * 10^-6/bar.

Limits

40 through 200.0 * 10^-6/bar

Select the No compensation option to turn off compressibility compensation.
