Tosoh TSKgel PW Aqueous SEC Guard Column for PW Columns, 13 μm , ID 7.5 mm x L 7.5 cm - 0006762

TSKgel PW Columns (Type of Polymer) for Analysis of Water-Soluble Polymers

TSKgel G2500PW - GMPW Guard Column for 7.5 mm ID columns, 12μm, Stainless Steel, ID 7.5 mm x L 75 mm 

Part Number: 0006762

TSKgel PW columns are composed of spherical, hydrophilic polymethacrylate beads. Particle sizes range from 12 µm for the smaller pore size columns to 17 µm for the larger pore size columns.

The main application areas for TSKgel PW columns are the analysis of water-soluble polymers, such as celluloses, acrylamides, glycols, dextrans, polyvinylalcohol, and oligosaccharides.

Recommended eluents for GFC of water-soluble polymers on TSKgel PW columns:

Type of Polymer	Typical Sample	Suitable Eluent
Nonionic hydrophilic	polyyethylene glycol	distilled water
Anionic Hydrophilic	sodium chondroitin sulfate, sodium alginate, carboymethyl cellulose, sodium polyacrylate, sodium hyaluronate	Buffer or salt solution (e.g. 0.1 mol/L NaNO3)
Anionic Hydrophobic	sulfonated lignin sodium salt, sodium polystyrenesulfonate	Buffer or salt solution with organic solvent (e.g. 20% CH3CN in 0.1 mol/L NaNO3)
Cationic Hydrophilic	glycol chitosan, DEAE-dextran, poly(ethyleneimine), poly(trimethylaminoethyl methacrylate) iodide salt	0.5 mol/L acetic acid with 0.3 mol/L Na2SO4 or 0.8 mol/L NaNO3
Cationic Hydrophobic	poly(4-vinylbenzyltrimethylammonium chloride), poly(N-methyl-2-vinylpyridinium) iodide salt	0.5 mol/L acetic acid with 0.3 mol/L Na2SO4
Amphoteric Hydrophilic	peptides, proteins, poly- and oligosaccharides, DNA, RNA	Buffer or salt solution (e.g. 0.1 mol/L NaNO3)
Amphoteric hydrophobic	blue dextran, collagen, gelatin, hydrophobic proteins, hydrophobic peptides	Buffer or salt solution with organic solvent (e.g. 20% CH3CN in 0.1 mol/L NaNO3 or 35-45% CH3CN in 0.1% TFA)
