TSKgel G-Oligo-PW is designed for high resolution separations of aqueous nonionic and cationic oligomers, and oligosaccharides such as hydrolyzed cyclodextrins. Because of the presence of cationic groups on the gel matrix, this column is not suited for separating anionic polymers. The PEG and PEO calibration curve is identical to that of G2500PWxl.
