Abstract:
A chromatographic analytical column, the column containing a packed bed of an anion-exchange chromatographic packing and capable of quantitative chromatographic separation of carbohydrates, which column comprises:a) Component A comprising support resin particles; andb) polymers including polymerized functionalized monomers each containing anion-exchange functional groups, each anion-exchange functional group comprising at least a first and second nitrogen group, wherein said first nitrogen group is a quaternary amine of the formula X-NRR'R"" and said second nitrogen group is selected from the group consisting of a primary amine of the formula X-NH.sub.2, a secondary amine of the formula X-NHR, a tertiary amine of the formula X-NRR' or a quaternary amine of the formula X-NRR'R"" wherein R, R' and R"" are straight or branched chained alkyl groups or cycloalkyl groups having from 1-10 carbons, and said polymers containing said anion-exchange functional groups are retained directly or indirectly on Component A.
