General description

Retention Mechanism: Anion-exchange
Sample Matrix Compatibility: Organic or aqueous solutions

  • A polymerically bonded quarternary amine that remains positively charged at all pH levels
  • Counter ion is Cl-
  • Ion exchange capacity is ∼ 0.14 meq/g
  • Commonly used when extracting weaker anions (e.g., carboxylic acids) that may not bind strongly enough to weaker anion-exchangers
  • Selectivity can be modified by changing the counter ion with the appropriate buffer during conditioning

Retention occurs through polar interaction between the sorbent and analytes. Typical sample matrices that can be employed in normal-phase SPE include hydrocarbon or fatty oils diluted in a solvent like hexane, isooctane, chlorinated solvent, THF, diethyl ether, or ethyl acetate.
