MP EchoChrom Alumina A, Activity: Super I, 1kg

MP EcoChrom™ Alumina A, activity Super I shows adsorbtion capacity approximately twice as high as that of MP EcoChrom™ Alumina A, Activity I. Their inital activity is kept in a very narrow range and their deactivation behavior is extremely constant. MP EcoChrom™ Alumina A, activity Super I are commonly used for purification processes of all kinds, including sample preparation for pesticides, and environmental analysis, solvent purification and all kinds of chromatography, requiring the highest precision and reproducibility. MP EcoChrom™ Alumina A catalyses a variety of reactions that are useful industrially. It is widely used to remove water from gas streams. Also used for its hardness and strength. It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond. Many types of sandpaper use aluminium oxide crystals. In chemistry laboratories, alumina is a medium for chromatography, available in basic (pH 9.5), acidic (pH 4.5 when in water) and neutral formulations , as well as for alcohols, hydrocarbons, steroids, alkaloids and natural pigments. Neutral alumina, (less active than the basic form) is useful for separation of aldehydes, ketones, quinones, esters, lactones, and glucosides. Acidic alumina, is the weakest and least often used type. Alumina is useful for separation of acid pigments and strong acids. It can cause polymerization, condensation and dehydration reactions. Neither acetone nor ethyl acetate should be used as eluants, the latter being subject to saponification. As well, it is used as a dosimeter for radiation protection and therapy applications for its optically stimulated luminescence properties.
