[Determination of the molecular weight of microbial polysaccharides using high performance exclusion chromatography]. / Opredelenie molekuliarnykh mass mikrobnykh polisakharidov s pomoshch'iu vysokoéffektivnoi ékskliuzionnoi khromatografii.

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.
