Field-Flow Fractionation: A Powerful Tool for Advanced Separation and Characterization of Nano and Polymer Samples

Gentle high resolution separation and fractionation of nanoparticles and macromolecules without stationary phase

Field-Flow Fractionation (FFF) is a separation technology that separates macromolecules or particles that are dissolved or dispersed in a suitable solvent in an open separation channel. Postnova is the exclusive manufacturer offering the whole range of FFF systems including Flow FFF, Thermal FFF, Centrifugal FFF and SPLITT FFF. FFF provides fast, gentle and high resolution separations of any particulate matter from 1 nm up to 100 µm in any liquid media in various matrices. Particularly in the fields of nanotechnology, nanomedicine and biotechnology, but also with increasingly complex questions in the area of food, polymer and environmental sciences, FFF technology has become a reliable alternative to established chromatographic separation methods like GPC/SEC or HPLC. Due to its broad application range and its compatibility with detection systems known from liquid chromatography such as Multi-Angle Light Scattering (MALS), Dynamic Light Scattering (DLS), Raman Microscopy, Refractive Index and ICP-MS.
