Representing more than a fifty percent share of world production of chromatography adsorbents, Selecto has become the dominant global leader in manufacturing of filtration media and elements.
Our products in this area include Classical Alumina, Classical Adsorbents, Silica, Activated Alumina and Technical Grade Aluminas.
For column chromatography, our Alumina is used with complete confidence and without any uncertainty, since we introduced our standardized Alumina of Activity I, and the various surface modifications of acid, basic and neutral.
Our high activity Alumina should be used for polar samples in nonpolar solvent systems for the purification of solvents. Lower activities of the Alumina can easily be obtained by the addition of polar media, especially water. Thus, the sorption system can be adjusted to meet the specific requirements by combining a sorbent of chosen activity with an appropriate eluant.
