Asymmetrical flow field-flow fractionation (asymmetrical flow FFF), connected on-line to multi-angle light scattering detection (MALS) was shown here to be an efficient method for size characterization of pullulan standards and dextrans ranging from 20 000 up to 2 000 000 in molecular mass. The characterization of molecular mass and the molecular mass distribution of these polysaccharides is often...
