Amide Columns
Excellent for Sugars | Most useful in ANP or RP modes | pH Stable
These Cogent, TYPE-C™, Amide Hydride™, HPLC columns have an ethyl
amide,
functional group, bonded to the silica hydride particle with direct,
silicon-carbon bonds.
This makes the stationary phase extremely stable, even in low pH conditions and
it doesn’t
make permanent associations with acetone like amino phases. Amide functional
groups are never
ionic under any chromatographic conditions providing some advantages.
The Cogent Amide™ phase is recommended for Aqueous Normal Phase (ANP mode) or Reversed-Phase (RP mode) separations of biomolecules, macro-molecules, carbohydrates, peptides, polysaccharides and tryptic digests.
