TSKgel SuperMultiporePW columns are packed with spherical, mono-disperse, polymethacrylate particles incorporating the proprietary multi-pore particle technology. Each particle each contains a wide range of pore sizes in order to provide near linear calibration curves. They belong to the semi-micro type of SEC columns (6 mm ID, 15 cm length) providing high theoretical plate numbers at half of the length of a conventional SEC column. The TSKgel SuperMultiporePW series comprises of three column types covering different molecular weight ranges (PW-N; PW-M, PW-H).
The main application area for TSKgel SuperMultiporePW columns is the analysis of water-soluble polymers, such as celluloses, acrylamides, glycols, dextrans, polyvinylalcohol, and oligosaccharides. Figure 1 shows the near linear calibration curves for the three SuperMultiporePW-type columns. Figure 2 shows the benefits of TSKgel SuperMultiporePW columns over a combination of different conventional SEC columns, namely the improved resolution and the smooth peak shapes without any inflection points.
