Increasing the resolution of field flow fractionation with increasing crossflow gradients [PDF]
, 2023 The resolution of flow field flow fractionation (flow FFF) depends primarily on the crossflow rate and its change over time. In this work we demonstrate a method for modulation of the crossflow rate during separation increases the peak-to-peak resolution
