Inertsil® Ph

Inertsil® Ph

Phenyl Column offering weak pi-pi interactions


Inertsil Ph has Phenethyl groups bonded to Silica gel which offers weak pi-pi interactions. Phenethyl group is a common functional group used for convetional Phenyl columns. Therefore Inertsil Ph has similar selectivity to other commercially available Ph columns on the market.

There are other Ph columns available from GL Sciences : Inertsil Ph-3 and InertSustain Phenyl are modified to bond Phenyl groups directly to Silica, thus provide different selectivities.
