This sorbent is composed of Aluminum oxide. Alumina, like silica, is an extremely polar sorbent. Its surface tends to be slightly more stable under high pH conditions than unfunctionalized silica. It is available in acidic (A = 4 ± 0,5 pH), basic (B = 9,5 ± 0,5 pH) and neutral (N = 7 ± 0,5 pH) formats.
