Compressibility (G1311A/B/C, G5611A, G5654A, G7111A/B) (Modular LC Quaternary Pump Valve Cluster Advanced)

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 G1311A/B/C, G5611A, G5654A and G7111A/B quaternary pumps, the default compressibility value is 100 * 10^-6. If the quaternary pump mixes solvents with large compressibility differences (e.g. water and methanol) we recommend that you use the default value.

Limits: 40 through 150.
