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.
