Activated Alumina – Flash Grade
Designed with a “tight” particle distribution of 32-63µm—it’s ideally suited for packing media in flash chromatography columns.
Alumina for flash chromatography is produced in two pH levels with higher initial activities (Loss on Ignition (LOI) is <1.7%):
- Neutral “active”
- Basic “active”
Additionally, the neutral grade is offered with a lower initial activity—the specific surface area is ~200 m²/g.
If acidic alumina is needed, ask Sorbtech for a procedure.
