Features
- It is a solid phase using alumina (Al2O3) and is an acidic type filler.
- Porous alumina is a highly polar adsorbent.
- Abundant surface electrons induce π-π stacking with aromatic rings, indicating strong polar retention and Lewis acidity.
- It is more stable under high pH conditions compared to unbound silica.
- Good retention of electron-rich compounds such as aromatic amines.
- Available in acidic (ALA), neutral (ALN) and basic (ALB) combinations, you can choose the right one for your specific application.
