Cleanert® NH₂ are silica-based, sorbent bonded with aminopropyl functional group.

• Can be used in normal or reversed phase mode
• Weak anion exchange
• Silica-based
• Sorbent bonded

Cleanert® NH₂ are silica based sorbent bonded with aminopropyl functional group. This sorbent can be used in either normal phase or reversed phase mode. It retains the analytes either by a polar adsorption (from non-polar solution) or by weak anion exchange (from aqueous solution). pKa=9.8.
