Structural Elucidation of Dextrans and other Polysaccharides using OMNISEC Multi- Detection GPC

Malvern’s OMNISEC triple detection GPC/SEC system provides outstanding molecular characterization data for the analysis of a series of dextran samples with molecular weights ranging from about 1 kDa up to over 650 kDa. Structural consistency was demonstrated using the Mark-Houwink plots of the samples. A gum arabic and pectin sample were analyzed to illustrate the structural differences between samples that can be observed. With the data provided by these measurements, researchers now possess greater insight to the molecular characteristics that define the behavior of these indispensable materials and can more accurately control crucial parameters such as molecular weight and structure. This allows better targeting of dextran products and grades to the applications for which they are best suited.
