Relative Selectivity of Various Counterions

AG® MP-1 neutral species and cations do not interact with the resin. In the chloride form of AG1, AG MP-1, and AG2 resin, the counterion on the resin is C1. A resin can be converted from one ionic form to another. Ususally the resin is used in an ionic form with a lower selectivity for the functional group than the sample ions to be exchanged. The sample ions are then exchanged onto the resin when introduced, and can be eluted by introducing an ion with higher affinity for resin or a high concentration of an ion with equivalent or lower affinity. The table below shows the relative selectivity of various counterions. In general, the lower the selectivity of the counterion, the more readily it exchanges for another ion of like charge. The order of selectivity can also be used to estimate the effectiveness for different ions as eulants, with the most highly selective being the most efficient. Finally, the order of selectivity can be used to estimate the difficulty of converting the resin from one form to another. Conversion from a highly selected to a less highly selected form requires an excess of the new ion.

Chelex Beads are made of a styrene divinylbenzene copolymer containing paired iminodiacetate ions, which act as chelating groups in binding polyvalent metal ions. The carboxylic acid groups of Chelex 100 Resin classify it as a weak cation exchange resin, but it differs from other exchangers in this class by featuring uniquely high selectivities for metal ions and much higher bond strengths.

Chelex 100 Chelating Ion Exchange Resin has a stronger selectivity for copper, iron, and other heavy metal ions over monovalent cations such as sodium and potassium. Its selectivity for divalent over monovalent ions is approximately 5,000 to 1, and it has a strong affinity for transition metals, even in highly concentrated salt solutions.

The following forms of Chelex 100 Resin Beads are available:

  • Analytical grade Chelex 100 Resin Beads — exhaustively sized, purified, and converted; suitable for accurate, reproducible analytical techniques
  • Biotechnology grade Chelex 100 Resin Beads — the analytical grade is certified to contain fewer than 100 microorganisms per gram of resin
