Tandem hollow-fiber flow field-flow fractionation

Journal of Chromatography A, 2011
Reinjection of one ore more collected fractions of eluted samples is recognized as a useful procedure in analytical separation techniques, among which field-flow fractionation (FFF), to improve the actual separation of complex samples. Hollow-fiber flow FFF (HF5) is a micro-channel subset of flow FFF (F4), which has recently reached a performance ...

Micro-Thermal Field-Flow Fractionation

Collection of Czechoslovak Chemical Communications, 2002
The 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 ...

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

Acoustic field-flow fractionation

Journal of Chromatography A, 1988
Abstract 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.

Two-dimensional field-flow fractionation

Journal of Chromatography A, 1990
Multidimensional 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, 1996
Field-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.
