Adjusting Compressibility
Adjusting Compressibility
Liquid chromatographic solvents are compressible under pressure. This
solvent compressibility produces a change in flow rate as the pressure
changes. To compensate for this effect, you can use the pump compressibility
setting to maintain a uniform and accurate flow regardless of the system
pressure. The compressibility setting can be accessed by using the Pump
Settings
button [
