APPLICATIONS IN CHROMATOGRAPHY
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 (ability to act as either an acid or a base) 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.

 

BATCH EXTRACTIONS AND DECOLORIZATION

The Chromatocel 150 and Chromatocel 230 series of products not only have applications in chromatography, they also have particle size distributions that make them ideal candidates for batch extractions or decolorizing. The 50-200 microns particle size range of Chromatocel 150 and Chromatocel 230 make them ideal for fast adsorption and efficient separation of the alumina once it has been used as an adsorbent.

QUALITY CHROMATOGRAPHIC ALUMINAS PROVIDE:
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.
