Features
- It is a solid phase using alumina (Al2O3) and is a neutral type filler.
- It's a very polar adsorbent like silica.
- Abundant surface electrons induce π-π interactions with aromatic rings, leading to strong polar retention and Lewis acidity.
- Compared to unbonded silica, alumina is more stable at high pH conditions and is suitable for aromatic amine extraction.
- Alumina is available in acidic (ALA), neutral (ALN), and basic (ALB) formulations and can be selected as appropriate for specific applications.
- Good retention of electron-rich compounds such as aromatic amines.
- It is more stable than unbonded silica at high pH conditions.
