TSKgel® PWXL-CP Columns for Cationic Polymer Analysis
TSKgel® PWXL-CP columns were specifically developed for the analysis of water-soluble cationic polymers. Composed of polymethacrylate beads, cationic groups are introduced on the surface of the TSKgel® PWXL-CP packing material to prevent adsorption of cationic polymers and allow elution under low salt conditions. These columns show high theoretical plate numbers, linear calibration curves and high durability because the base resin is the same as that used in the TSKgel® PWXL series columns.
Three columns are available within the TSKgel® PWXL-CP series, each with a different particle size, separation range and exclusion limit, allowing polymers within a wide molecular mass range to be separated and characterized.
The calibration curves for polyethylene glycol and oxide are shown for each of the three TSKgel® PWXL-CP columns.
