Tosoh TSKgel SP-STAT Column, 7 μm, ID 4.6 mm x L 10 cm - 21964

Ion Exchange Chromatography

TSKgel SP-STAT Cation Exchange Column, 7 μm, ID 4.6 mm x Length 10 cm

TSKgel SP-STAT columns are packed with 7 and 10 µm hydrophilic non-porous resin particles of which the surface consists of an open access network of multi-layered cation exchange groups. The innovative bonding chemistry, combined with a relatively large particle size, results in a respectable loading capacity and a low operating pressure.

Applications for the TSKgel SP-STAT columns include the separation of proteins, protein aggregates, charge isomers of monoclonal antibodies, PEGylated proteins, and peptide digests.

Product Attributes: Matrix: hydrophilic polymer Particle size (mean): 7 and 10 μm Pore size: non-porous Functional group: sulfopropyl Counter ion: Na pH range: 3.0-10.0 Static binding capacity (mg  Lysozyme/mg dry gel): ca. 15 (7 µm) ca. 10 (10 µm)  Small ion capacity: 23 ueq/g dry gel pKa: 4.0
