Bond Elut NH2

Bond Elut NH2 SPE from Agilent Technologies

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.
