Experiment, theory, and simulation of a flow-electrical-split flow thin particle separation device.

Herein, we describe the simulation of a novel flow-electrical-split flow thin (Fl-El-SPLITT) separation device and validate it using existing theory and experimentation for the first time using polystyrene particles of 28 and 1000 nm diameters. The fraction of particles exiting selected ports with DC El-SPLITT is predicted with existing theory, but the theory does not include AC fields, nor does it incorporate the use of crossflows. Using DC fields the El-SPLITT simulation and theory calculated transition points result in the same values.
