TSKgel PWxl-, PW-type and SuperMultiporePW columns are the columns of choice for analyses of water-soluble polymers.  All TSKgel polymer-based gel filtration columns are prepared from polymethacrylate resin. TSKgel PWxl- and PW-type Use higher efficiency TSKgel PWxl-type columns for optimal resolution, to reduce analysis time, or in sample limited applications. Use TSKgel 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). TSkgel PWxl-CP columns TSKgel PWxl-CP columns have been chemically modified to improve recovery of cationic polymers. TSKgel SuperMultiporePW columns These columns are packed with particles containing a wide range of pore sizes. Three semi-micro columns within series allow wide separation range from high MW polymers to oligomers.

Highlights: All TSKgel PW-type columns Hydrophilic methacrylate beads. Particle sizes are 4-8μm for TSKgel SuperMultiporePW columns, 7-13μm for TSKgel PWxl and PWxl-CP columns, and 12-17μm for TSKgel PW-type Higher % crosslinking for smaller particle size TSKgel PWxl-type resins Stable from pH 2 to 12 Eluent: water or buffer (up to 20% methanol/80% aqueous) TSKgel 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). TSKgel SuperOligoPW column is more hydrophilic compared to TSKgel G-Oligo-PW column TSKgel PWxl-CP columns Minimal adsorption of cationic polymers TSKgel SuperMultiporePW columns Extended linear calibration curves result in better accuracy for molecular mass determination

TSKgel PW and PWxl	TSKgel PWxl-CP	TSKgel SuperMultiporePW
As TSKgel PW-type columns, there are seven TSKgel PWxl-type columns varying in pore size from less than 100Å to more than 1000Å. Mixed-bed columns are also available. The TSKgel PWxl product line also offers specialty columns for analyzing: Carbohydrate oligomers DNA and RNA fragments Oligosaccharides - new column! TSKgel PWxl-CP columns have the same base resin as the TSKgel PWxl columns and were specifically developed for the analysis of water-soluble cationic polymers and allow elution under low salt conditions. Available TSKgel PWxl-CP-type columns and pore sizes: TSKgel G3000PWxl-CP [200Å] TSKgel G5000PWxl-CP [1000Å] TSKgel G6000PWxl-CP [>1000Å] TSKgel SuperMultiporePW columns are packed with monodisperse 4, 5 or 8μm particles in semi-micro dimensions, enabling high speed and high resolution separation. Available TSKgel SuperMultiporePW columns: TSKgel SuperMultiporePW-N  TSKgel SuperMultiporePW-M TSKgel SuperMultiporePW-H

Application Overview -- Gel Filtration Chromatography with TSKgel columns

TSKgel SuperMultiporePW columns are packed with particles that contain a broad range of pore sizes for the analysis of water-soluble polymers.

TSKgel SuperOligoPW columns are for the determination of molecular mass of aqueous oligomers and low MW aqueous polymers.
