WebJan 1, 2016 · Asymmetric Flow Field-Flow Fractionation (A4F) For the fractionation we used a commercial A4F system (Postnova Analytics GmbH, GER). It consists of an AF2000 focus system (manual injection valve, PN7520 inline degasser, PN1130 tip/focus pump). WebField flow fractionation. 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.
