The ideal, unified Field-Flow Fractionation (FFF) analysis, suggested that a novel operational-mode exists at the largest particle sizes. Therefore, our collaborators in Dr. Michel Godin’s laboratory constructed a 18micron microfluidic channel to to test this prediction for polystyrene colloids subject to a gravitational field and to determine how well the retention theory would match experimental data across multiple operational-modes.
Our work has recently been submitted for publication. The manuscript presents experimental data, MPCD simulations and a modified, numerical retention theory to build up a consistent picture of FFF of large colloids eluting through microfluidic devices.
