摘要：
An embodiment discloses a fluid pump for use in a fluid separation system for separating compounds of a fluidic sample in a mobile phase, the fluid pump comprising a reciprocatable piston configured for moving the mobile phase, a pump drive configured for driving the reciprocatable piston, and a control unit configured for controlling the pump drive so that pressure ripples in a pressure profile of the fluid pump are at least partially compensated to thereby bring the pressure profile in accordance with a predefined target characteristic. Another embodiment discloses a fluid pump for use in a fluid separation system for separating compounds of a fluidic sample in a mobile phase, the fluid pump comprising a reciprocatable piston configured for moving the mobile phase, and a pump drive configured for driving the reciprocatable piston using a piezomechanism.
