Molecular weight determination and Purification of Polysaccharide by HPLC

Purpose
Molecular weight determination of polysaccharide by size exclusion chromatography; Purification of the polysaccharide according its molecular weight for further structure analysis (glycosyl composition, glycosyl linkage or NMR, et al)

Methods Used:
High performance liquid chromatography (HPLC) is used for size exclusion chromatography (SEC).

Amount of Sample Required for Analysis:
If you have no knowledge of the nature of the sugar constituents of your sample and you desire an ideal analysis, a minimum of 500 micrograms of carbohydrate is required. If you have considerably smaller amounts of carbohydrate sample, we can make special arrangements to determine the composition of your sample. Please contact us to discuss your specific requirements, and do not let limited sample amount deter you from requesting our services.
