Carbo Sep CHO-820 CA Carbohydrate, SS 200 mm x 7.8 mm

The CarboSep CHO 820 HPLC column 200x7.8mm, 9µm, is a Ca²⁺ form with 8 % cross-linking, designed for robust ligand-exchange separations of carbohydrates. CarboSep CHO 820 can be used as a more highly cross-linked calcium-selective resin for mono- and disaccharides as well as sugar alcohols. Typical applications include the analysis of fructose, fermentation products, sweeteners, starch hydrolysates and other aqueous 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.
