Carbo Sep Coregel-87N, SS 300 mm x 7.8 mm

The CarboSep CHO 87N HPLC column 300x7.8mm, 9µm, is a Na+ form with 8 % cross-linking for ligand-exchange chromatography of carbohydrates. CarboSep CHO 87N is suitable for the separation of mono-, di- and oligosaccharides in highly aqueous mobile phases where a higher degree of sodium selectivity is required. Typical applications include sugar profiles in foodstuffs, fruit juices, syrups, fermentation broths and hydrolysed carbohydrate samples.

Features and Benefits

• Polymer-based ligand-exchange resins for carbohydrates
• Various counterions, such as Na+, Ca2+, Pb2+, and K+, for targeted selectivity
• Cross-linking degrees of 4, 6, 7, and 8% to adjust porosity, resolution, and robustness
• Suitable for monosaccharides, disaccharides, and oligosaccharides

Additional Notes

The CarboSep series uses polymer-based packing materials with defined counterions and degrees of cross-linking. Unlike conventional silica phases, retention is not based on hydrophobic surface interactions, but rather on ligand exchange and size- or structure-dependent interactions between the carbohydrates and the polymer resin. This allows sugars, sugar alcohols, and oligosaccharides to be separated in highly aqueous eluents. The polymer backbone used is designed for routine applications in carbohydrate analysis; compatible CarboSep pre-column cartridges help keep matrix components out of the main column.
