Wyatt Asymmetric Field Flow Fractionation (AF4)

Field flow fractionation (FFF) separates molecules using perpendicular flow on membranes or hollow-fibres for separation, with various detectors providing molecular size and mass data.

Description

Field flow fractionation (FFF) is a rapid but gentle separation technique similar to size exclusion chromatography that uses a membrane or hollow-fibre instead of a column. In this technique, a perpendicular flow is used to separate molecules on either a membrane (AF4) or a hollow-fibre (HF5).

The FFF system in the lower campus laboratory uses a Shimadzu Prominence HPLC system to deliver the solvent and inject samples. A Wyatt Dualtec module is used to control the different flows across the membrane or hollow-fibre. The system also has various detectors that provide information about the size and mass of molecules.
