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,

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.

Sedimentation Field Flow Fractionation: Applications
Science, 1982Sedimentation field flow fractionation is a powerful, new, high-resolution separation method for a wide variety of colloids, micelles, particulates, and soluble macromolecules of biological interest. Advances in instrumentation allow sedimentation field flow fractionation operation with rotor speeds up to 32,000 revolutions per minute (∼85,

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 ...

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 ...

Acoustic field-flow fractionation
Journal of Chromatography A, 1988Abstract Field-flow fractionation (FFF) in a standing acoustic wave field with the use of radiation pressure was studied. With this force field across the channel, values characterizing the effectiveness of the separation were obtained. In this situation the separation process resembles conventional FFF.

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

Two-dimensional field-flow fractionation
Journal of Chromatography A, 1990Multidimensional field-flow fractionation (FFF) is described in two major forms: one in which different separative stages are coupled together and one in which two independent displacements, at least one of them FFF, are carried out in a generally planar channel structure.

Tutorial: Field-Flow Fractionation
The Chemical Educator, 1996Field-flow fractionation (FFF) is a family of techniques used to characterize macromolecules, colloids, and particulate materials, primarily by size, but in some cases by composition as well. FFF has many similarities to chromatography, but it also has several unique differences.

Field-Flow Fractionation (FFF)
2017Field-Flow Fractionation techniques (FFF) are size-based separation methods first described in 1966 by Giddings. They belong to the family of liquid chromatographic techniques, but they are operated without any stationary phase.Yet, they have the unique ability to separate an extremely broad range of molecules, macromolecules and particles, and in ...
