High Molar Mass Starches Analyzed in Batch and Microbatch Modes

High Mass Starch Zimm Plot

Polysaccharides (of which starch is an important example) are carbohydrates whose molecules consist simply of a number of monosaccharide residues, which are bound together. These molecules are frequently very large in molar mass and, as such, may not lend them selves to separation via size-exclusion chromatography (SEC) because they elute beyond the exclusion limits of currently-available columns. When this is the case, Wyatt Technology’s DAWN® can be employed in a batch or “micro-batch” mode to produce weight-average molar masses and z-average sizes for very high molar mass starches, with out separation.
