Sedimentation Field Flow Fractionation of Liposomes

Science, 1982
Quantitative 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 ...

Study on structure-function of starch by asymmetrical flow field-flow fractionation coupled with multiple detectors: A review.

Carbohydrate Polymers, 2019
Starch is one of the most abundant, renewable, non-toxic, and biodegradable polysaccharides, mainly comprising amylose and amylopectin. The physicochemical properties and structure of starch affect the quality of starch-based products.

Development of Electrical Field-Flow Fractionation

Analytical Chemistry, 2000
Electrical field-flow fractionation (ElFFF) results for a series of polystyrene latex beads are presented. To first approximation, retention behavior can be related to conventional FFF theory, modified to account for a particle-wall repulsion effect.

Sedimentation Field Flow Fractionation of DNA's

Science, 1984
Sedimentation field flow fractionation (SFFF) is a method for purifying and providing mass or size distribution information on samples containing particulates or soluble macromolecules. Since SFFF separations are based on simple physical phenomena related to first principles, molecular weight (or particle sizes) can be determined without ...

Flow field-flow fractionation: Recent applications for lipidomic and proteomic analysis

Trends in Analytical Chemistry (TrAC), 2019
Flow field-flow fractionation (FlFFF) is a versatile size-based separation method suitable for biological macromolecules including proteins/protein aggregates, DNA, subcellular organelles, extracellular species, and whole cells.

Electrical Field-Flow Fractionation of Proteins

Science, 1972
Protein separation has been achieved by electrical field-flow fractionation, a heretofore unrealized separation technique. Some advantages of this method relative to electrophoresis are the low voltage required, the lack of adverse heating and support effects, and the existence of the method as an elution technique.

Exosome Isolation: Cyclical Electrical Field Flow Fractionation in Low-Ionic-Strength Fluids.

Analytical Chemistry, 2018
The influence of buffer substitution and dilution effects on exosome size and electrophoretic mobility were shown for the first time. Cyclical electrical field flow fractionation (Cy-El-FFF) in various substituted fluids was applied to exosomes and other

Capillary electrophoresis and asymmetric flow field-flow fractionation for size-based separation of engineered metallic nanoparticles: A critical comparative review

Trends in Analytical Chemistry (TrAC), 2018
In the characterization of nanomaterials, size and size distribution are among the most important parameters. A high-resolution technique is essential for the accurate determination of size distribution for a polydisperse nanoparticle suspension ...

Sedimentation Field Flow Fractionation: Applications

Science, 1982
Sedimentation 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,

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.
