The innovative multi-pore particle synthesis technology which Tosoh scientists pioneered, has now been extended to TSKgel SuperMultiporePW columns for water-soluble polymer analysis. Three semi-micro columns varying in linear range are available within this series, enabling high speed and high resolution analysis with lowered solvent consumption. The base material of each TSKgel SuperMultiporePW column is polymethacrylate.

A wide molecular mass range can be analyzed with the three different TSKgel SuperMultiporePW columns, from high molecular mass water-soluble polymers to oligomers. The packing material in the TSKgel SuperMultiporePW columns is more hydrophilic than that of TSKgel PWxl series columns, which further reduces the chance of adsorption of hydrophilic polymers.

Applications Analysis of PVP-15 polymer Hydrophobic interaction causes partial adsorption of PVP-15 polymer on TSKgel G3000PWxl and G2500PWxl columns, while the absence of adsorption on the TSKgel SuperMultiporePW-N column suggests that the particle surface is more hydrophilic than the conventional columns.
