Carbo Sep CHO 87P 200, Lead Form SS 200mmx7.8mm

The CarboSep CHO 87P HPLC column 200x7.8mm, 9µm, is a Pb²⁺ ligand-exchange phase with 8 per cent cross-linking, designed for demanding carbohydrate and sugar alcohol separations. CarboSep CHO 87P is used when high Pb²⁺ selectivity and a more cross-linked polymer resin are required for the separation of closely related saccharides. Typical applications include the analysis of sweeteners, starch hydrolysates, oligosaccharides, 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.
