Exsil Avanti Phenyl

Aromatic Selectivity for Advanced Reversed-Phase HPLC and UHPLC

Exsil Avanti Phenyl is a high-efficiency phenyl-bonded silica stationary phase developed for selective reversed-phase HPLC and UHPLC separations, particularly of aromatic and conjugated compounds. By combining hydrophobic retention with enhanced π–π interaction capability, this phase provides complementary selectivity to traditional C18 or C8 materials.

The aromatic phenyl surface enables additional interaction mechanisms such as π–π stacking, dipole interactions, and shape recognition effects. This makes Exsil Avanti Phenyl especially suitable for structurally related aromatic analytes, isomer separations, polyaromatic compounds, pharmaceuticals, and heterocyclic molecules. The balanced retention profile allows efficient resolution without excessive analysis time. Manufactured on the advanced Exsil Avanti high-purity spherical silica platform, the phase delivers excellent mechanical strength, uniform packing quality, and reproducible chromatographic performance under both HPLC and UHPLC conditions. The optimized surface chemistry reduces unwanted secondary interactions, resulting in sharp peaks and consistent retention behavior across gradient and isocratic methods.

Exsil Avanti Phenyl combines aromatic interaction capability with high-efficiency silica technology — delivering enhanced selectivity, reproducible performance, and precise reversed-phase separations for complex organic analytes.
