Grom Resin Pb++, IEX is a polymer-based HPLC column functionalized with sulfonic acid groups in the lead form (Pb²⁺). It is optimized for the ligand-exchange separation of mono- and disaccharides, oligosaccharides, and sugar alcohols, offering unique selectivity and high-resolution separation of structurally similar carbohydrates. The silanol-free polymer matrix ensures excellent chemical stability, even at elevated temperatures, and allows for reproducible retention behavior in purely aqueous mobile phases.
This column is a preferred solution in food analytics, fermentation monitoring, and bioethanol production where precise carbohydrate profiling is essential.
Grom Resin Pb++, IEX delivers outstanding carbohydrate separation performance – an ideal choice for laboratories using HPLC or IC for sugar and polyol analysis.
