HPLC Columns


TSKgel Q-STAT columns are packed with 7 and 10 µm non-porous resin particles of which the surface consists of long hydrophilic chains of open access network of multi-layered quaternary ammonium anion exchange groups. The innovative bonding chemistry, combined with a relatively large particle size, results in a respectable loading capacity and a low operating pressure, making these columns suitable for all HPLC and FPLC systems.

Applications for the TSKgel Q-STAT columns include the separation of proteins, peptides, low molecular weight nucleic acids, aggregates and charge isomers of monoclonal antibodies, PEGylated proteins, oligo DNA, and siRNA.
