In chromatography: Subsequent developments
This technique is called field-flow fractionation. It has been termed one-phase chromatography because there is no stationary phase. Its main applications are to polymers and particulate matter. The method has been used to separate biological cells, subcellular particles, viruses, liposomes, protein aggregates, fly ash, colloids, and pigments.

In separation and purification: Field separations
Field-flow fractionation consists of a series of methods based on a field applied perpendicular to a flow stream in a narrow channel. Because of friction at the channel walls, the velocity of the liquid will be faster in the center than at the walls. In…
