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 G-DNA-PW is a specialty column designed for the separation of large polynucleotides such as DNA and RNA fragments of 500-5000 base pairs. TSKgel G-DNA-PW is a smaller particle size version of TSKgel G6000PWxl.
