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

TSKgel PWxl columns are composed of spherical, hydrophilic polymethacrylate beads. The main application area for TSKgel PWxl columns is the analysis of water-soluble polymers, such as celluloses, acrylamides, glycols, dextrans, polyvinylalcohol, and oligosaccharides. See the table on the TSKgel PW page for typical samples and suitable eluents. Figure 1 shows the calibration curves for all TSKgel PWxl-type columns. Figure 2 shows the benefits of TSKgel PWxl columns over PW columns, namely the improved resolution due to the smaller particle sizes used in PWxl columns.

TSKgel G4000PWxl columns are ideally suited for analysis of water-soluble linear polymers with molecular weights up to 300,000 Da. The smaller particle size of TSKgel PWxl-type columns provide 1.7x higher resolution than their PW counterpart, making TSKgel PWxl-type columns more suitable for analytical purposes.
