NUCLEOSIL® NH2 / NH2 RP Columns

Polar aminopropyl modified silica for reversed phase and normal phase chromatography:
Normal phase chromatography with hexane, dichloromethane or 2-propanol as mobile phase for polar compounds such as substituted anilines, esters, chlorinated pesticides
Reversed phase chromatography of polar compounds like carbohydrates in aqueous-organic eluent systems
Anion exchange chromatography of anions and organic acids using common buffers (e.g., acetate or phosphate) in conjunction with organic modifiers (e.g., acetonitrile)

Available pore sizes 100, 120 and 300 Å, available particle sizes 3 µm, 5 µm, 7 µm and 10 µm, 
pH stability at 20 °C: 2–8, carbon content 3.5 %

Separation mechanism based on polar interactions, hydrophobic interactions and weak ion exchange interactions
