Field‐flow fractionation for nanoparticle characterization
Journal of Separation Science, 2021AbstractThis review presents field‐flow fractionation: The elements of theory enable the link between the retention and the characteristics of the nanometer‐sized analytes to be highlighted. In particular, the nature of force and its way of being applied are discussed.

Cyclical electrical field flow fractionation
Electrophoresis, 2005AbstractCyclical electrical field flow fractionation (Cy/ElFFF) is demonstrated in a standard electrical field flow fractionation (ElFFF) channel for the first time. Motivation for the use of alternating current (AC) fields in a traditionally direct current (DC) technique are discussed.

Field-flow fractionation (FFF) is a family of instrumental techniques that separates and characterizes macromolecules, colloids, and particles (macromaterials) on an analytical scale (Colfen and Antonietti, 2000; Schimpf et al., 2000). As illustrated in Fig. 1, the FFF channel has a ribbon-shaped geometry, typically with length 30-50 cm, breadth 1-3 cm,

Field-flow fractionation and biotechnology
Trends in Biotechnology, 2005The gentle separation mechanism has made field-flow fractionation particularly suited to samples of biotechnological interest, from proteins and nucleic acids to viruses, subcellular units and whole cells. Recent progress in field-flow fractionation technology, as well as the development of coupled techniques combining field-flow fractionation ...
