Dynamic Adsorbents is the industry leader in the use of alumina for adsorption chromatography. While also selling a comprehensive line of silica gel products that are the highest quality in the industry and unique in providing customers with a detailed analysis from each lot of silica gel provided the customer, we recommend the use of since according to “August 2003 New Horizons and Challenges in Fundamental Analysis and Monitoring” (see bottom of page), Alumina is the most effective adsorbent used for this purpose. Silica, along with 3 metal oxides (alumina, titanium and zirconia), are all used in the stationary phase of adsorption chromatography. Attributes of silica include the following: • High sample loading • Fewer unwanted reactions during separation • Wide range of chromatographic forms of silica wide range of surface areas and average pore diameters • The hydroxyl group in silica is attached to silicon hydroxyl groups are either free or hydrogen bonded • The silicas used are a
