XBridge BEH C18 sorbent can be used over an entire range of mobile phase pH (1 to 12). The trifunctionally bonded C18 ligand provides with a universal column for most HPLC separations and gives you the widest usable pH range, superior low pH stability, and ultra-low column bleed. The XBridge BEH C8 sorbent is less retentive compared to the XBridge BEH C18 sorbent.

Supplier: WATERS

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.
