Aminopropyl silica functions as both a weak anion exchanger (at low pH) and a normal-phase sorbent. It is particularly effective for retaining organic acids, carbohydrates and fatty acids while passing non-polar interferences.

Applications: Aflatoxins in feed and food (standard method), sugars and organic acids in beverages, fatty acid clean-up, sulfonamide antibiotics.
