Exsil 80 Phenyl is a silica-based HPLC stationary phase with an 80 Å pore size and a phenyl-bonded surface, designed to provide aromatic selectivity through π–π interactions in addition to hydrophobic retention. This interaction profile enables enhanced resolution of aromatic and conjugated compounds and offers orthogonal selectivity compared to conventional alkyl-bonded phases such as C8 or C18.
The controlled pore structure and high surface area support high chromatographic efficiency, sharp peak shapes, and reproducible retention behavior for small-molecule separations. Exsil 80 Phenyl is particularly well suited for method development where alternative selectivity is required to resolve closely related or structurally similar analytes.
Exsil 80 Phenyl provides distinct aromatic selectivity, high efficiency, and reliable reproducibility, making it a valuable tool for challenging small-molecule HPLC separations.
