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 isocratic pump and gradient pump, the default compressibility value is 100 * 10-6. If the gradient pump mixes solvents with large compressibility differences (e.g. water and methanol), we recommend that you use the default value.
Limits: 0 through 150.
