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 capillary and nanoflow pumps, the default value is 50 * 10-6 for channel A and 115 * 10-6 for channel B. Always set the compressibility value for both channels.
Limits: 40 through 150.
