SG81 Ion Exchange Paper, sheet SG81 ion exchange sheetsis a 0.27 mm combining cellulose and large pore silica gel for separations in which both partition and adsorption are important. Simultaneous development of multiple samples on the same sheet under identical conditions. Sequential development of the same samples with different solvents and/or different concentrations of the same solvent. Suitable for twodimensional 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. A novel paper (0.27 mm thick) combining cellulose and large pore silica gel. 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. Flow rate is 110 mm/30 min. Grade SG81
