DeactiSil™ is an identical selectivity to the Inertsil® HPLC column. Deactisil C4 has Butyl groups bonded to Silica gel and is able to achieve separation without adsorption. Conventional C4 columns lack durability, however, Deactisil C4 was developed to excel in durability as well as inertness.
DeactisilTM Phenyl has identical selectivity to Inertsil Ph and has Ethyl Phenyl groups bonded to Silica gel which offers weak pi-pi interactions. The Ethyl Phenyl group is a common functional group used for conventional Phenyl columns. Therefore Inertsil Ph has similar selectivity to other commercially available Ph columns.
