Postnova Analytics Field-Flow Fractionation and light scattering detector for particle, nanoparticle, macromolecules and polymer characterisation. Determination of molar mass, size, composition and elemental distribution of complex samples.
Field-flow fractionation (FFF), a gentle tool for separation and characterization of macromolecules and particles, has attracted increasing interest in recent years due to its broad dynamic size range and the utilization of an "open channel" void of packing materials or stationary phase. In this ...
Field-flow fractionation (FFF) is a separation method used for the fractionation of macromolecular or particulate samples, usually in a long and narrow channel between two parallel plates. A carrier liquid flows through this channel, while a force acts at right angle to the flow. Separation ...
Field-flow fractionation (FFF) is a versatile means of size- based separations, capable of fractionating viral particles, liposomes, and lipid nanoparticles, proteins, and more. The EclipseTMsystem is the foundation of FFF-MALS, a technique for the separation and characterization of macromolecules an...
FFF principle Different separation forces Depending on the Field-Flow Fractionation method which is used, different force fields (liquid flows, centrifugal forces, temperature gradients or gravity fields) are used and applied perpendicular to the separation channel. Under the influence of these force fie...
Field-flow fractionation (FFF) is a family of high-resolution techniques capable of separating and characterizing materials in the macromolecular and colloidal range, and beyond. Applications have spanned a 10 15 -fold mass range, extending from molecules under 1000 molecular weight to particles 100...

2.2.1Field Flow Fractionation Field flow fractionation(FFF) is a class of analytical methods suitable for the separation andcharacterization of nanomaterialsand shares the most common likeness withliquid chromatography(LC). The mechanism for separation, however, departs from the classical enthalpic interact...
