GromSil 120 Phenyl-1 FE is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with high-purity, fully porous silica featuring a 120 Å pore size and bonded with phenyl ligands. The phase includes full endcapping (FE) to suppress silanol activity and enhance peak symmetry, particularly for basic or polar analytes.
Combining hydrophobic and π–π interaction mechanisms, this column provides unique selectivity for aromatic compounds, isomers, and molecules with conjugated systems — making it especially useful in pharmaceutical and natural product analysis.
With its balanced aromatic selectivity and minimized secondary interactions, GromSil 120 Phenyl-1 FE from Dr. Maisch HPLC GmbH is an excellent choice for reversed-phase applications involving π-rich or structurally complex analytes.
