HPLC Guard Column-Kit Inertsil Ph-3, 100Å, 5 µm, 4 x 10mm, incl. Holder and 2 Guard Cartridges

GL Sciences Inertsil Ph-3 have phenyl groups directly bonded to the silica gel which provides pure reverse phase characteristics that are c ritical to resolving highly polar compounds like acidic and basic pharmaceuticals. T he 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.
