HPLC Guard Column Inertsil Ph-3, 100Å, 10 µm, 3.9 x 20 mm

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.
