      Journal of Chromatography A. Volume , 17 January , Pages Characterization of cationic polymers by asymmetric flow field-flow fractionation and multi-angle light scattering—A comparison with traditional by: The retention time, t r, of a polymer in field-flow fractionation is approximated by, (1) t r t 0 = w 2 V x 6 D V 0 where w is the channel thickness, V x and V 0 are the volumetric cross-flow and channel volume, respectively, and D is the diffusion coefficient of the polymer. Greater retention, and thus increased resolution, can be achieved by increasing cross-flow. Note that retention time Cited by:

    A comprehensive, practical approach to three powerful methods of polymer analysis and characterization. This book serves as a complete compendium of three important methods widely used for the characterization of synthetic and natural polymers--light scattering, size exclusion chromatography (SEC), and asymmetric flow field flow fractionation (A4F). Field-flow fractionation, abbreviated FFF, is a separation technique where a field is applied to a fluid suspension or solution pumped through a long and narrow channel, perpendicular to the direction of flow, to cause separation of the particles present in the fluid, depending on their differing "mobilities" under the force exerted by the field. It was invented and first reported by J. Calvin.

    Asymmetric Flow Field-Flow Fractionation (AF4) was applied to fractionate five different maize hybrids of varying AMY:AMP ratio. When coupled to detection by multi-angle light scattering and refractive index (MALS–RI), it was possible to determine mass percentage and the average weight-average molar mass (M w) without the need for Cited by: and particle size range of the technique. As a consequence, there is a tendency to observe lower amounts of aggregates and smaller particle sizes in SEC than e.g., in AUC or FFF. AF4 - The Modern Alternative Asymmetric Flow Field-Flow Fractionation (AF4) is an innovative separation technology, which clearly overcomes the prob-.

The theory for AF4 was conceived in and was established in It is a separation technique based on the theory of field flow fractionation (FFF). AF4 is distinct from FFF because it contains only one permeable wall so the cross-flow.

Asymmetric flow field-flow fractionation (AF4) enables to analyse polymers with very high molar masses under mild conditions in comparison to size exclusion chromatography Author: Stepan Podzimek. The most common fractionation method used with MALS is HPLC size exclusion chromatography (SEC).

SEC-MALS provides accurate distributions of molar mass and size (root mean square radius R g), as opposed to: Standard SEC, which depends on column calibration by reference standards.
