General description

Chelex®100 sodium form is a chelating resin made of a styrene and divinylbenzene copolymer. It has a pair of iminodiacetate ions that chelate polyvalent metal ions, shows greater metal ion selectivity, and has a stronger binding force.

Application

Chelex®100 sodium form is commonly used:
  • As an ion exchange resin, in wastewater treatment due to its high affinity for metal ions
  • For the extraction and purification of DNA
  • As adsorbent in protein purification
  • In determination of trace elements in marine water
