Aluminum oxide is a chemical composed of aluminum and oxygen (Al2O3), and activated alumina consists of several transitional phases of aluminum oxide. Activated aluminas are used in many industries that manufacture high purity products.

Aluminum oxide is a powerful amphoteric (ability to act as either an acid or a base) oxide, with powdered alumina having several application areas, including being used as a solid phase, adsorbent, desiccant and catalyst.


A variety of solid phase materials can be used in chromatography. Aluminum oxide, also referred to as alumina, is often used because of its amphoteric nature. Optimized particle size, surface area, pH, and purity make aluminas particularly effective for separation of small molecules, peptides, lipids, alkaloids, and a wide variety of other materials.


The Chromatocel 230 and Chromatocel 150 series of products are often used in chromatography, batch extractions, and decolorization. The 50-200 microns particle size range of our Chromatocel 230 and Chromatocel 150 products make them ideal for fast adsorption and efficient separation of the alumina once it has been used as an adsorbent.

Please contact us at aluminumoxide@porocel.com if you would like to see the Application Bulletins for our products or for a Porocel representative to contact you to discuss your Aluminum Oxide needs.


Reproducible separations:
Tight controls over process parameters enable Porocel to deliver products with low batch to batch variability.

High Quality products:
High quality aluminum oxide products protect users from introduction of outside contaminants.  Quality assurance systems and qualified cleaning processes maintain the purity of the aluminas allowing for cleaner separations and can reduce washing steps.


Desirable particle size distributions:
Low fine content allows for efficient separations with reduced band tailing. The lowering of fines in high quality chromatographic alumina also reduces process back pressures and can prevent premature filling during column packing.
