PolarSil columns are based on polar modified silica and ideal for the organic GPC/SEC separation of low to medium molar mass resins and lignins with molecular weights from 100 to 1,000,000 Da using polar organic solvents. Multiple column configurations are available to match your specific application, including two particle sizes, 3 and 5 μm, and three porosities, 100, 300, and 1,000 Å as well as two different linear/mixed-bed columns.
SDV columns are useful for a wide variety of polymer analyses in nonpolar and medium polar organic solvents. These GPC columns are made from a styrene-divinylbenzene copolymer network and are available in three particle sizes (3, 5, and 10 μm) and a range of porosities to meet many organic GPC and SEC polymer analysis needs, including for polystyrene, polyvinyl chloride, polycarbonate, elastomers, resins, and more. The molecular weight range for SDV columns is 100 to 30,000,000 Da. SDV columns meet USP L21.
SUPREMA columns are ideal for the aqueous GPC/SEC analysis of neutral and anionic polymers, such as PEO, PEG, pullulan, dextran, polyacrylamide, hyaluronic acid, polyacrylic acid, and carboxymethyl cellulose. These acrylate copolymer-based columns are available in three particle sizes, 3, 5, and 10 μm, individual porosities between 30 and 30,000 Å and different linear/mixed-bed columns, to meet a variety of applications needs, including polymers ranging from 100 to 30,000,000 Da. SUPREMA columns meet USP L25, L37, L38, L39, tolerate high buffer concentrations, pH 2 to 12, temperatures up to 80 °C, and organic solvents (up to 100% methanol or acetonitrile).
NOVEMA Max columns are made of NH-functionalized acrylate copolymer. These columns are suitable for the aqueous GPC/SEC analysis of cationic polymers, such as polymeric quaternary ammonium compounds, poly(DADMAC), polyvinylpyridine, chitosan, and poly(ethylene imine), with molecular weights ranging from 100 to 30,000,000 Da. Available in two particle sizes and different porosities as well as linear/mixed-bed options, NOVEMA Max columns are flexible to meet a variety of application needs. NOVEMA Max columns meet USP L23, tolerate high buffer concentrations, pH 2 to 12, temperatures up to 80 °C, and organic solvents (up to 100% methanol or acetonitrile).
MCX columns are suitable for the aqueous GPC/SEC analysis of strong polyanions such as poly(styrene sulfonate), lignin sulfonate, modified starches, acids, alcohols, and pectins. This sulfonated styrene-divinylbenzene copolymer-based GPC column can be used for sulfonated polymers with molar masses ranging from 100 to 5,000,000 Da and are available in two particles sizes with a range of porosities to meet your polymer analysis needs. MCX columns meet USP L22, tolerate high buffer concentrations, pH 1 to 13, temperatures up to 80 °C, and organic solvents (up to 100% methanol or acetonitrile).
