HPLC columns made in Japan

Inertsil PH-3 Columns
  • Virtually perfect peak shape for most bases and acids
  • 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 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.
