Tracer Carbohydrates column is based on a Polymeric Coating Chemically Bonded Silica Base packing, that includes in its structure primary amino groups.
This polymeric coating protects surface silica packing against attacks coming from aqueous/organic mobile phases used in the separation of sugars.
Keeping the selectivity of a conventional NH2 column, Tracer Carbohydrates have a longer lifetime.
This column can be also washed with eluents lightly basic to eliminate acidic impurities irreversibly linked with the packing that degrade very quickly any standard NH2 columns.
• Higher Stability
• Better resolution in disaccharides analysis
