Tosoh TSKgel G2000PW Aqueous SEC Column, 12 μm, ID 7.5 mm x L 30 cm - 05761

Gel Filtration Chromatography

TSKgel G2000PW Aqueous SEC Column, 12 μm, ID 7.5 mm x Length 30 cm
Guard Column Available - 06763

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 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 G2000PW is ideally suited for analysis of water-soluble polymers with molecular weights up to 2,000 Da.
