TSKgel G3000PWXL-CP
The TSKgel G3000PWXL-CP column was specifically developed for the analysis of water-soluble cationic polymers with molecular weights up to 100,000 Da. Composed of 7 µm polymethacrylate beads, cationic groups are introduced on the surface of the TSKgel G3000PWXL-CP packing material to prevent adsorption of cationic polymers and allow elution under low salt conditions.
This columns shows 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.
