solid phase



Amino, Sorbent, Orpheus, 1/pkg

The strong polarity of the aminopropyl functional group allows for both normal phase and anion exchange retention mechanism. NH2 acts as a weak anion exchanger at a pH of 9.8. The functional groups become positively charged at a pH below 9.8. Ideal sorbent choice for quick release of strong anions such as sulfonic acids which can possibly be irreversibly retained by strong anion exchangers. Typical application includes extraction of carbohydrates from food, plants aqueous extract, and beverage.
