Reprospher 100 Phenyl-Hexyl-e is a high-performance reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with ultra-pure, fully porous spherical silica bonded with phenyl-hexyl ligands and fully endcapped to deactivate residual silanol groups. This phase combines strong hydrophobic retention from the hexyl chain with π–π interaction selectivity from the phenyl group, providing superior separation of aromatic and structurally related compounds. The endcapping ensures excellent peak symmetry, especially for basic and polar analytes, while maintaining robust retention and reproducibility for a wide variety of compounds.
Reprospher 100 Phenyl-Hexyl-e from Dr. Maisch HPLC GmbH offers powerful aromatic selectivity with excellent peak shape – ideal for challenging reversed-phase HPLC separations involving aromatic and structurally similar analytes.
