Carbo Sep CHO782 Carbohydrate & Biomass Analysis, SS 300 mm x 7.8 mm

The CarboSep CHO 782 HPLC column (300 × 7.8 mm, 7 µm) is a Pb²⁺ ligand-exchange phase with 7 per cent cross-linking on a polymeric backbone. The average degree of cross-linking of the CarboSep CHO 782 lies between that of 6 per cent and 8 per cent materials and is optimised for demanding carbohydrate and biomass samples. Typical applications include sugar alcohols, mono- and disaccharides, as well as carbohydrate profiles in confectionery, syrups, foodstuffs and fermentation 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.
