  2. 1. Asymmetrical Flow Field-Flow Fractionation and Multiangle Light Scattering for Molar Mass Analysis of Polysaccharide Derivatives

    Author : Mats Andersson; Industriell Produktion; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polysaccharide derivatives ethylhydroxyethyl cellulose; molar mass analysis; asymmetrical flow field-flow fractionation; multiangle light scattering; polymer size distribution; Polymer technology; biopolymers; Polymerteknik;

    Abstract : Molar mass and molar mass distribution of polymers are parameters of fundamental importance as they influence the performance of the polymer in applications. Polysaccharide derivatives are a class of polymers that have attracted significant scientific and commercial interest as they can be manufactured from a wide range of abundant sources in nature and thereby often are both cheap and biocompatible.

  4. 2. Asymmetrical Flow Field-Flow Fractionation in the Application to Biological Macromolecules

    Author : Cecilia Arfvidsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Bioteknik; Biotechnology; biotechnology; recombinant protein production; molecular weight; Escherichia coli; ribosomes; glutenin; asymmetrical flow field-flow fractionation; multiangle light scattering;

    Abstract : Asymmetrical flow field-flow fractionation (AsFlFFF) is especially useful in the application to biological macromolecules due to the absence of a stationary phase in the separation channel. As a result no upper exclusion limit occurs and low shear forces affect the sample components. READ MORE

  5. 3. On the Aggregation of Cereal β-Glucan and its Association with other Biomolecules : A Study using Asymmetric Flow Field-Flow Fractionation (AF4)

    Author : Claudia Zielke; Avdelningen för livsmedel och läkemedel; []
    Keywords : ß-glucan; polysaccharides; dietary fiber; field flow fractionation; Asymmetric flow field-flow fractionation AF4 ; Multiangle light scattering MALS ;

    Abstract : During recent years, numerous studies have shown the ability of dietary fiber toprotect the colon from disease and to improve intestinal health. Beneficial healtheffects, such as the lowering of blood cholesterol levels and a reduction in the risk of coronary heart disease, are often directly related to cereal β-glucan, one of the major components of dietary fiber found in oat and barley.
