Inertsil® Ph-3

Inertsil® Ph-3

Phenyl column offering strong pi-pi interactions


Phenyl-bonded phase provides pi-pi interactions occuring between Phenyl groups and analytes. Inertsil Ph-3 has Phenyl groups directly bonded to Silica gel whereas common phenyl columns have Phenylalkyl groups bonded to Silica gel. Therefore, compared with common phenyl columns, the separation by Inertsil Ph-3 is based more strongly on pi-pi interactions.

InertSustain® Phenyl, another Phenyl column of GL Sciences, shows different selectivity as it has Phenyl groups more densely on the Silica surface.
