TSKgel PWXL- and PW-type columns are the columns of choice for analyses of water-soluble polymers.  All TSKgel polymer-based gel filtration columns are prepared from polymethacrylate resin.

PWXL- and PW-type

• Use higher efficiency PWXL-type columns for optimal resolution, to reduce analysis time, or in sample limited applications.
• Use PW-type columns when analysis time is not critical, when sample mass is not limited, to collect fractions, or to obtain maximum number of plates (at the expense of analysis time).

PWXL-CP columns

• PWXL-CP columns have been chemically modified to improve recovery of cationic polymers.

Highlights:

• PW, PWXL and PWXL-CP columns
  • Hydrophilic methacrylate beads.
  • Particle sizes are 7-13μm for PWXL and PWXL-CP columns, and 12-17μm for PW-type. 
  • Higher % crosslinking for smaller particle size PWXL-type resins.
  • Stable from pH 2 to 12
  • Eluent: water or buffer (up to 20% methanol/80% aqueous)
  • G6000PW is available in PEEK column hardware for ultra-low sample adsorption during virus analysis.
  • Temperatures up to 80˚C (50˚C for TSKgel G-DNA-PW).
• PWXL-CP columns
  • Minimal adsorption of cationic polymers.
