Effect of wall velocities on the determination of optimal separation times in electrical field flow fractionation (EFFF)

Abstract: Electrical field flow fractionation (EFFF) has two perpendicular driving forces that help to produce an optimal separation of solute in a mixture [Giddings, Science 1993; 260:1456-1465. For Couette flow based devices, the ratio of the velocity of the capillary walls offers an extra parameter that can be exploited to enhance the efficiency of EFFF applications. The analysis of the effects of this parameter on optimal times of separation is the subject matter of this contribution. The use of this additional para… Show more

“…The electrical field is introduced in electrical FFF (EFFF) as the functional field perpendicular to the carrier flow. The separation effect of EFFF on macromolecules, colloids and nanoparticles has been explored [18][19][20][21][22][23]. There is a micrometre-thin, rectanglelike channel in EFFF.…”
