HPLC columns made in Japan

Inertsil Ph Columns
  • Part of the Original Inertsil 2-Series of Phases
  • Unique selectivity
  • Exceptional physical and chemical durability provides long column life
  • Vast database of chromatographic applications available to assist in method development
  • Very low operating back pressure


Phenyl column offering weak pi-pi interactions.

Inertsil Ph has Phenethyl groups bonded to Silica gel which offerethyl group is a common functional groupor 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.
