AG 3, AG 4, and Bio-Rex 5 Resin
Weakly Basic and Intermediate Basic
Anion Exchange Resin Instructions
Introduction
AG 3-X4 and AG 4-X4 resins are weakly basic
anion exchangers. These resins can exchange anions,
such as organic acids, with weak interactions, allowing
easy elution and regeneration. They will also adsorb
mineral acids, such as hydrochloric acid and perchloric
acid, to yield a neutralized solution. Bio-Rex 5 resin is an
intermediate basic anion exchanger, which also
exchanges anions, such as iodide, bromide, and chloride,
with weak interactions, allowing easy elution and
regeneration.
Technical Description
AG 3-X4, AG 4-X4, and Bio-Rex 5 resins are all
analytical grade purity. They have been exhaustively
sized, purified, and converted to make them suitable for
accurate, reproducible analytical techniques. AG 4-X4
resin is also available in Biotechnology Grade,
Analytical Garde resin which has been further processed
