Copure® ALA, ALN, ALB, Alumina

High-activity porous alumina features surface electrons that can form π-π interactions with aromatic rings, exhibiting strong polar retention capabilities and Lewis acid characteristics. Compared to unbonded silica, alumina is more stable in high pH environments, making it suitable for the extraction of aromatic amine compounds. Alumina is specially treated to offer three types: acidic (ALA), neutral (ALN), and basic (ALB), each tailored to match different target compound properties.

Details
