GromSil Phenyl-2 CP is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, based on high-purity, fully porous silica and bonded with phenyl ligands using a classic bonding approach. This phase provides strong π–π interaction and moderate hydrophobic retention, offering alternative selectivity compared to C18 or C8 phases — particularly useful for aromatic, conjugated, or structurally similar analytes.
Its stable surface chemistry ensures consistent performance in LC-MS and UV workflows and is well suited for method development and routine separations.
With its proven bonding chemistry and π-selective retention, GromSil Phenyl-2 CP from Dr. Maisch HPLC GmbH is a robust and versatile option for reversed-phase separations involving aromatic and structurally complex molecules.
