TSKgel® gel filtration columns, PW-type

These columns are designed for GFC of water soluble organic polymers, polysaccharides, oligosaccharides, DNA and RNA. They are based on a hydrophilic polymethacrylate matrix, which is stable from pH 2 to 12 and in aqueous eluents with up to 50% polar organic solvent.

• TSKgel® PWXL range is preferred for analytical purposes, due to the increased efficiency and resolution
• The 600 mm length TSKgel® PW columns are recommended for their increased loading capacity for preparative work
• The mixed bed TSKgel® GMPW and GMPWXL columns are useful for samples with a broad molecular weight range
• TSKgel® PWXL-CP columns are especially suited to the separation of cationic polymers

TSKgel® PW and PWXL:
Seven TSKgel® PW columns vary in pore size from less than 100 Å to more than 1000 Å. A mixed-bed column is also available. TSKgel® PWXL columns cover the same pore size ranges as PW but have smaller particle sizes and are thus more efficient. The TSKgel® PWXL product line also offers speciality columns for analysing carbohydrate oligomers - TSKgel® G-Oligo-PW and for DNA and RNA fragments - TSKgel® G-DNA-PW.

TSKgel® PWXL-CP series:
TSKgel® PWXL-CP columns are designed to facilitate the separation of water soluble cationic polymers by SEC. They are produced in three different pore sizes for different molecular weight ranges. By incorporating a cationic functionality on the polymethacrylate particle surface, ionic adsorption of the polymers is eliminated. This modification results in high recovery for cationic polymers and enables elution under low salt conditions.

TSKgel® SuperMultiporePW series:
TSKgel® SuperMultiporePW columns are packed with monodisperse polymethacrylate particles, each containing a wide range of pore sizes to cover different molecular weight ranges. Multi-pore particle technology is the best way to achieve near linear SEC calibration curves, without the peak disturbances which typically occur due to a mismatch of pore sizes from coupled columns with different molecular weight ranges.
