These useful silica-hydride HPLC columns have an amide functional group bonded directly to the particle with a direct silicon-carbon bond.

The Cogent Amide phase is very stable and is recommended for Aqeous Normal Phase(ANP) or Reversed-Phase (RP) separations of biomolecules or macromolecules including carbohydrates, peptides, polysaccharides or tryptic digests.
