Multi-angle light scattering coupled to size exclusion chromatography (SEC-MALS) or field-flow fractionation (FFF-MALS) is the most
robust and reliablemethod for characterizing heterogeneous distributions typical of biopolymers such as polysaccharides,
hyaluronic acid, cellulose or polylactic acid.
Since MALS determines molar mass and size without regard for elution time, it does not depend on identifying and qualifying
well-characterized molecular standards for each type of biopolymer and solvent. The analysis of mass and size at each elution
volume permits ASTRA® software tocalculate various characteristic values of the distribution such as weight-, number- or
z-averaged mass and size.
Is your biopolymer branched or otherwise structured? Quantitative determination of conformation can also be obtained from
MALS analysis throughthe measured relationship between size and molar mass.
