Abstract
A mixer arrangement for use in a chromatography system includes a first frequency targeting mixer including a first flow channel coupled between an inlet and an outlet and a second flow channel coupled between the inlet and the outlet, the second flow channel including a volume offset region configured to delay fluid propagation through the second flow channel, wherein the volume offset region is configured to reduce or eliminate fluidic compositional oscillations in a compositional solvent stream that depart from a desired composition at a first target frequency, and a residual noise targeting mixer fluidically connected in series to the frequency targeting mixer, the residual noise targeting mixer configured to dampen aperiodic baseline noise in the compositional solvent stream.
