TSKgel G-Oligo-PW Aqueous SEC Guard Column, 13 μm, ID 6 mm x Length 4 cm
For TSKgel G-Oligo-PW Column - P/N: 08031
TSKgel Top-Off, 1g Available - P/N: 08035

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 G-Oligo-PW is designed for high resolution separations of aqueous nonionic and cationic oligomers, and oligosaccharides such as hydrolyzed cyclodextrins. Because of the presence of cationic groups on the gel matrix, this column is not suited for separating anionic polymers. The PEG and PEO calibration curve is identical to that of TSKgel G2500PWxl.
