• 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

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. Figure 1 shows the calibration curves for all TSKgel PWxl-type columns. Figure 2 shows the benefits of TSKgel PWxl columns over PW columns, namely the improved resolution due to the smaller particle sizes used in PWxl columns.

TSKgel GMPWxl  is a mixed bed scouting column for aqueous water-soluble linear polymers.  Its pore volume is accessible to polymers ranging from molecular weights of 500 up to 8,000,000 Da.  By quickly categorizing the MW profile of an unknown sample, TSKgel GMPWxl allows the selection of the most appropriate TSKgel PWxl column for best results in a routine analysis.  TSKgel GMPWxl is also used for the analysis of samples with broad MW distributions.
