Field-flow fractionation and biotechnology

open access: yesTrends in Biotechnology, 2005
The 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 ...

Cyclical electrical field flow fractionation

ELECTROPHORESIS, 2005
AbstractCyclical 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.

Asymmetric Flow Field-Flow Fractionation in the Field of Nanomedicine

Analytical Chemistry, 2014
Asymmetric flow field-flow fractionation (AF4) is a widely used and versatile technique in the family of field-flow fractionations, indicated by a rapidly increasing number of publications. It represents a gentle separation and characterization method, where nonspecific interactions are reduced to a minimum, allows a broad separation range from several

Field‐programmed flow field‐flow fractionation

Journal of Microcolumn Separations, 1995
AbstractA flow field‐flow fractionation (FIFFF) system capable of accurate and reproducible flowrate programming has been assembled and tested. This modified system consists of three computer‐controllable pumps, two that regulate the incoming and outgoing cross flowrates and one that controls the channel flowrate.

Field-Flow Fractionation

TrAC Trends in Analytical Chemistry, 1994
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

Journal of Fluid Mechanics, 1983
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

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 of macromolecules

Journal of Chromatography A, 1989
Field-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
