Carbo Sep CHO 682 USP 100, Lead Form SS 100mmx7.8mm

The CarboSep CHO 682 HPLC column 100x7.8mm, 7µm, is present in the lead(II) (Pb²⁺) form and utilises a 6 % cross-linked polymer resin for ligand-exchange chromatography of sugars. The 6 per cent cross-linking degree of CarboSep CHO 682 promotes high selectivity for unknown or complex carbohydrate profiles. Areas of application include carbohydrate profiles in foodstuffs, sweeteners, starch hydrolysates and biotechnological 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.
