Flow Field-Flow Fractionation is a uniquely versatile means of size-based separations, capable of fractionating and characterizing proteins and aggregates, liposomes, emulsions, viral particles, polysaccharides, nanoparticles, polymer latex particles, colloidal soil suspensions, chemical mechanical polishing slurries, and many more – with no stationary phase and almost no shear.

The Eclipse® DualTecTM system offers both Hollow-Fiber Flow-FFF (HF5) and Asymmetric Flow-FFF (AF4) techniques. Both may be integrated into one instrument and coupled seamlessly to the most advanced light scattering detector for determination of molar mass and nanoparticle size, Wyatt’s DAWN® HELEOS® II.
