DAI's alumina are superior to other aluminas on the market.
The DAI team wrote the book when it comes to alumina. Literally, not figuratively. For over 25 years innovations by the DAI team have played a major role in the exponential growth of the use of alumina for separation technologies.
DAI’s Alumina is at the forefront of Separation Technology. A major reason for the exponential growth in the use of alumina for chromatography has been our contribution to standardizing the manufacturing process. Our efforts have resulted in standardized grades of alumina having well controlled and defined:
Constant Deactivation behavior
Controlled Chromatographic Parameters
Controlled Surface Area
Ability to customize for specific applications
Dynamic Adsorbents is the only company offering a full range of alumina products that are superior to anything in the marketplace and can handle a much wider range of applications.
Quality Control - DAI controls the full manufacturing process
Adsorbents, Inc. Aluminas are manufactured and Quality Assured providing world class Laboratory and Pilot Process chromatographic materials. We control the manufacturing process from raw material to finished product, unique in our industry.

k' - uniform capacity • - reproducible
RS- improved resolution
N - excellent performance
Careful attention is paid to quality control
procedures reproducible performance regardless of the technique
used, especially when transferring from one technique to
Dynamic Adsorbents Inc. (DAI) has formulated a specialty proprietary adsorbent (Alumina C) allowing PCBs to be removed safely from contaminated sites, offering several advantages over alternative methods. More info
Dynamic Adsorbents, Inc. Aluminas are unique products; e.g., Super I, Std Act I, etc: High activity Alumina is useful for eluting polar samples in nonpolar solvents, and for the purification of solvents. Lower activities of Alumina can readily be obtained by the addition of polar media, especially water. Thus, each problem can be resolved via the adjustment of the sorption system, as required for each problem.
Super activity I aluminas are unique as DAI's products; they demonstrate approximately twice the capacity as compared to Standard activity l;
