Technology details
Name: Field-Flow fractionation
Category:
Feedstock: Biowaste
Product: Biomass in different physicochemical fractions

Field-Flow Fractionation (FFF) is a separation technology without a stationary phase for dilute suspensions. The suspensions can be fractionated according to their physicochemical properties such as charge, chemical composition, density, molar mass, and size. Beside analytical purposes the FFF can also be utilised for preparative purposes.

Feedstock

Suitable feedstocks are heterogeneous mixtures of different substances in form of dilute suspensions (solids in liquid). Depending on the applied process and technology solids can be usually separated in the nm-µm-range.
