Excellent for sugars | Most useful in NP 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) which is the same as HILIC or Normal-Phase (NP mode) separations of biomolecules, macro-molecules, carbohydrates, peptides, polysaccharides and tryptic digests.
Other sizes and configurations including prep and process columns are available. Please contact Customer Service for details.
NOTE: Our technical support team strongly recommends that the Cogent column filter that protect HPLC columns, included with each column, be used with all HPLC columns whenever possible.
