Field flow fractionation (FFF) is a chromatography-like separation technique which is designed for fractionation of macromolecules, colloids and particles. The principle is simple. A laminar flow of carrier liquid between two walls, separated by c. 0.1 mm, creates a parabolic velocity profile. rcs veteran affairsField-flow fractionation, abbreviated FFF, is a separation technique which does not have a stationary phase. It is similar to liquid chromatography as it works on dilute solutions or suspensions of the solute. Separation is achieved by applying a field (hydraulic, centrifugal, thermal, electric, magnetic, gravitational, ...) … See more FFF is applicable in the sub-micron range (from 1 nm to several microns) in the "normal" mode or up to 50 microns in the so-called steric mode. The transition from normal to steric mode takes place when diffusion becomes … See more FFF does not work for small molecules, because of their fast diffusion.
