Its total volume capacity can move in the range 0.04 to 0.15 mmol/ml, adequate mass capacity is 0.15 to 0.45 mmol/g dry matter. According to customer´s demand the sorbents volume capacity can be varied in the range given by the mass capacity and water content. Water content moves in connection with the volume capacity in the range 58 to 85 %. Iontosorb SHP can be used in the chromatographic separations of proteins, peptides, amino acids, nucleic acid components and other biological substances.
