Whatman™ Grade SG81 Ion Exchange Chromatography Paper

Whatman™ Grade SG81 ion exchange chromatography paper is novel paper combining cellulose and large pore silica gel. This ion exchange chromatography paper is not charged, but binds polar molecules from less polar solvent. Suitable for separations in which both partition and adsorption are important, including the separation of phospholipids, steroids, phenols and dyes. Paper allows for simultaneous development of multiple samples on the same sheet under identical conditions. Sequential development of the same samples with different solvents or different concentrations of the same solvent is possible. Suitable for two dimensional chromatography (change in direction of the solvent front) with possible improved resolution. Used in enzyme assays to separate product from reactant by charge or polarity. Flow rate is 110mm/30-Minutes. Thickness: 0.27mm
