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 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 ...

If different contaminant species are subject to different transverse drift rates (e.g. gravitational settling), then there is a tendency for the species to separate out. The efficiency of this separation depends upon the relative shapes of the longitudinal concentration distributions.

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,

Separation Science and Technology, 1976
Abstract Field-flow fractionation (FFF) is a separation method first described in 1966 (I). FFF is an elution technique, like chromatography, and the experimental sequence of pump, column, detector, and fraction collector is much like that used in chromatographic operations (2-4).

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.

Field-flow fractionation of macromolecules
Journal of Chromatography A, 1989Field-flow fractionation (FFF) is a versatile family of techniques, applicable to macromolecules, colloids, and cell-sized particles. This paper focuses specifically on the applicability of FFF to macromolecules. Following a brief description of the principles of FFF, the characteristics of FFF that bear on its efficacy in separating macromolecules are

Micro-Thermal Field-Flow Fractionation
Collection of Czechoslovak Chemical Communications, 2002The effect of miniaturization of the separation channel on the performance of thermal field-flow fractionation (TFFF) is substantiated theoretically. The experiments carried out under carefully chosen experimental conditions proved the high performance of the separation of polymers within an extended range of molar masses from relatively low up to ...

Sedimentation Field Flow Fractionation of Liposomes
Science, 1982Quantitative analyses of the particle size distributions of liposomes were performed in 30 to 60 minutes by exponential-field sedimentation field flow fractionation. This gentle new separation method exhibits great potential for the high-resolution fractionation and the size or molecular weight analysis of a wide variety of biological macromolecules ...
