Alumina, like silica, is an extremely polar sorbent. The alumina surface tends to be slightly more stable under high pH conditions than unfunctionalised silica. The small particle size of the Bond Elut™ Alumina range ensures high extraction efficiency even when small bed masses are used.

• Available in acidic (A), basic (B) and neutral (N) formats
• High extraction efficiency
• Better high pH stability than unfunctionalised silica
