title: [Determination of the molecular weight of microbial polysaccharides using high performance exclusion chromatography].
abstract: An automatic method of determining the molecular weight parameters (Mw, Mn) of microbial polysaccharides such as dextran, pullulan was developed based on the use of high performance size-exclusion chromatography on the two types of columns: Zorbax PSM 60 + 300 + 1000 and SynChropack GPC 100 + 500 + 1000. The Mw and Mn values were determined for a number of domestic and foreign dextran preparations. Changes in the molecular weight of pullulan and hydroxyethylstarch resulted from acid and enzymatic hydrolysis were estimated.
