Inertsil phenyl-3, 100 X 4.6um, 3um

Phenyl column offering strong pi-pi interactions.

The phenyl-bonded phase provides pi-pi interactions occurring 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.

Benefits

• 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

Just like InertSustain Phenyl, Inertsil Ph-3 have phenyl groups directly bonded to the silica gel which provides pure reverse phase characteristics that are critical to resolving highly polar compounds like acidic and basic pharmaceuticals. The near perfect phenyl phase coverage on this material results in symmetric, narrow peaks for even the most polar compounds while using simple eluents like aqueous acetonitrile or methanol.
