Bond Elut NH₂ is a weak anion exchanger and is a good choice for retention of very strong anions that may be irreversibly retained on other anion exchange sorbents.

• Normal phase or anion-exchange sorbent
• Weaker anion exchange than SAX
• Amenable to separating structural isomers

Bond Elut NH₂ is a weaker anion exchanger than sorbents such as SAX (a quaternary amine sorbent that is always charged), and is therefore a better choice for retention of very strong anions, such as sulfonic acids, which may retain irreversibly on a SAX sorbent. Similar to diol an SI sorbents, bond elut NH₂ is excellent for the separation of structural isomers.
