TSKgel® PWXL Columns for Analysis of Water-Soluble Polymers
TSKgel® PWXL columns are composed of spherical, hydrophilic polymethacrylate beads. The main application area for these columns is the analysis of water-soluble polymers, such as celluloses, acrylamides, glycols, dextrans, polyvinylalcohol, and oligosaccharides. See the table on the TSKgel® PW columns page for typical samples and suitable eluents.
The figures below show the calibration curves for all TSKgel® PWXL columns.

Specialty TSKgel® PWXL Columns
TSKgel® G-DNA-PW is available for the analysis of large polynucleotides, such as DNA and RNA fragments of 500-5,000 base pairs.
TSKgel® G-Oligo-PW is the preferred column for the high resolution analysis of aqueous nonionic and cationic oligmers and oligosaccharides such as hydrolyzed cyclodextrins.
TSKgel® SuperOligoPW contains smaller particles and semi-micro dimensions compared to the TSKgel G-Oligo-PW column, enabling high speed separations with high resolution of aqueous oligomers.
The mixed-mode column, TSKgel® GMPWXL, has an extended linear calibration range, suitable for samples with a broad molar mass (MM) distribution and unknown samples.
