Amberlite® XAD4, Pore size: 100 Å 20 - 60 mesh ion-exchange resin, Supelco®

Dodavatel: Merck

Popis: Nonionic macroreticular resin that adsorbs and releases ionic species through hydrophobic and polar interactions; usually used under isocratic conditions.

Ion exchangers

Dodavatel: Merck

Popis: In general, ion exchangers consist of a cross-linked polymer matrix with a uniform distribution of fixed ionic groups sited throughout the resin structure. These must be balanced by a similar number of ions of the opposite charge, (counter ions) to maintain electrical neutrality. Cation exchangers therefore, exchange and enrich only cations, anion exchangers only anions. In contrast adsorber resins have a non ionic, but depending on the structure, a somewhat polar character, and don't adsorb stoichiometrically both: anions, cations, as well as uncharged compounds.
