Gel Filtration Chromatography

TSKgel G2500PWxl Aqueous SEC Column, 10 μm

Tosoh's polymer-based gel filtration columns are either prepared from polymethacrylate resin (TSKgel PW, PWXL and PWXL-CP) or from hydroxylated polyvinyl (TSKgel Alpha and SuperAW) resin. Each resin type can be synthesized in a wide variety of different pore sizes. The four major product groups also differ from one another in average particle size. A more important distinction is, however, the range of solvents that can be used with each product line.

Hydroxylated polymethacrylate beads

  • From water to 20% (under some conditions 50%) organic solvents

    • TSKgel PWXL and 
      TSKgel PWXL-CP, 7-13       μm
    • TSKgel PW, 12-17 μm

Hydroxylated polyvinyl beads

  • Water and most polar organic solvents

    • TSKgel SuperAW, 4-9 μm
    • TSKgel Alpha, 7-13 μm

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.
