HPLC Columns

TSKgel G-Oligo-PW

The TSKgel G-Oligo-PW column 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 TSKgel G-Oligo-PW column has a base material of hydroxylated polymethacrylate, can be used in a maximum of 20% organic, and is shipped in water.
