(A) Relationship between the DEP-FFF elution time and frequency for DS19 cells (●) for different flow rates. At the crossover frequency f0 the DEP force is zero and elution times correspond to those measured by conventional sedimentation-FFF (★). Solid lines show simulated elution characteristics based upon the analysis given in the text. Dotted lines show elution characteristics predicted by earlier theory that ignored hydrodynamic lift. (B) The Clausius-Mossotti factor reveals the relative DEP force experienced by cells as a function of DEP frequency. The influence of this on cell elution characteristics is evident in (A).
