Each product group contains columns with distinctly different pore sizes, and one mixed-bed column.

TSKgel PW columns are composed of spherical, hydrophilic polymethacrylate beads. Particle sizes range from 12 µm for the smaller pore size columns to 17 µm for the larger pore size columns. TSKgel G4000PW is ideally suited for water analysis of water-soluble polymers of less than 300,000 Da molecular weight.
