In the case of a constant crossflow, a constant flow rate of 0.5 mL/min was applied for 50 min. In the case of a linearly decreasing crossflow, a starting flow rate of 0.6 mL/min drops decreases linearly to 0 mL/min over 50 min. In the case of an exponentially decreasing crossflow, a starting flow rate of 0.6 mL/min drops decreases exponentially to 0 mL/min over 50 min. The samples were characterized online via DLS and UV/Vis extinction spectroscopy (400 to 800 nm).
