Waters™ Ultrahydrogel™ are polymer-based columns for size exclusion chromatography with aqueous eluents. The base material is a hydroxylated polymethacrylate gel, which is available with different pore sizes. Waters Ultrahydrogel columns are ideal for analyzing aqueous-soluble samples such as oligomers, oligo- and polysaccharides, as well as cationic, anionic and amphoteric polymers. Ultrahydrogel columns are available in the dimension 7.8x300 mm.
