Effective ion exchange resins for challenging purification and separation processes
DuPont™ AmberChrom™ resins are available in two families of resins based on either a methacrylate or aromatic structure. A variety of particle and pore sizes are offered in each group.
DuPont™ AmberLite™ resin is an insoluble, strongly acidic, sodium form cation exchange resin supplied as a dry powder. It is suitable for use in pharmaceutical applications, both as an active ingredient and as a carrier for basic (cationic) drugs.
DuPont™ AmberLyst™ Ion Exchange Resin is a highly porous, granular, weak base anion exchange resin based on crosslinked phenol-formaldehyde polycondensate. Its ion exchange activity is due almost entirely to tertiary amine groups. Consequently, it exhibits minimal strong base capacity. Regeneration with little more than stoichiometric amounts of alkali is rapid and complete. It has proven more efficient than conventional polystyrene resins in a variety of applications.
DuPont™ AmberSep™ is a resin of macroporous structure. Its polystyrenic matrix, crosslinked with DVB, contains aminophosphonic groups. The chemical nature of these groups is such that they form complexes with metal ions. AmberSep™ may be distinguished from aminodiacetic resins by its specificity for various cations and by the greater stability of the complexes formed with cations of low atomic mass.
DuPont™ AmberSorb™ is used for the removal of organic compounds from liquid or vapor streams in drinking water or chemical processing.
DuPont™ AmberTec™ is a uniform particle size, gel, strong acid cation exchange resin for single bed and mixed bed demineralization applications.
