Eclipse® devices carry out field-flow fractionation (FFF) of macromolecules and nanoparticles ranging in size from 1 nm – 1000 nm, with no stationary phase, eliminating shear and non-ideal column packing interactions. Integrates with top-quality HPLC pumps and autosamplers.

A wide choice of flat and hollow-fiber channels separates both soluble and colloidal components, from nanogram to milligram quantities.

Eclipse AF4

A versatile system for separating macromolecules, proteins, colloids, and nanoparticles.

The Eclipse™ AF4 is optimal for all standard asymmetric-flow field-flow fractionation (AF4) separations as well as frit-inlet channels and semi-preparative AF4. Combined with industry-leading HPLC equipment and Wyatt’s unique multi-angle light scattering detectors, the Eclipse AF4 excels at characterizing difficult samples.

The ultimate separation system for proteins, polymers and nanoparticles.

Uniquely Versatile

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.

Nanoparticle Size

The Eclipse™ DualTec™ 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® instrument.
