About this item
SymmetryShield™ columns feature Waters' patented embedded polar group technology that shields the silica's residual silanols from highly basic analytes at improves overall peak shape. Additionally, by placing the embedded polar group close to the silica surface, the activity of the surface silanols is further reduced. This imparts selectivity and retention that is different compared to the Symmetry® C18 ligand.
