=== Origin and composition === | |||
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 between the nm-µm range. The FFF is usually applied to separate cells, different kind of nanoparticles, polymers, and proteins for analytical and preparative purposes. | Suitable feedstocks are heterogeneous mixtures of different substances in form of dilute suspensions (solids in liquid).
