Dynamic Adsorbents’ Silica Judged Best in Industry

Dynamic Adsorbents’ silica gel products have been found by independent laboratory analysis to be demonstrably superior due to a low amount of fines compared with major competitors and with the least amount of trace metal impurities compared with all other competitor’s products.

When announcing the results, DAI President Dr. Mark Moskovitz said, “Our line of adsorbents offer precisely what chromatographers have come to expect from all DAI products – the best alumina, the best silica and the best bonded phase packing material available for academic or industrial usage.”

A recent study by an independent research laboratory found that DAI’s silica products were the industry leaders in their categories, surpassing competitors by almost every measure in consistency, purity and performance.

DAI silica provides you with the purest material you can find for your separation needs. An analysis of silica from all major vendors reveals that the level of unwanted iron, lead and copper contaminants is much less than that of our competitors – in some cases strikingly so! There is no finer brand silica gel commercially available. We are certain that you will be pleased with our performance, our price, and our service.
