ReproSil Star Phenyl-Ether is a silica-based HPLC column with a phenyl-ether bonded phase, developed for demanding pharmaceutical and biotechnical applications. The phenyl-ether functionality combines π–π interactions of the aromatic ring with additional dipole and hydrogen-bonding contributions from the ether linkage. This dual-interaction mechanism offers enhanced selectivity for aromatic, polar, and moderately hydrophobic compounds.
Built on high-purity, mechanically stable silica, ReproSil Star Phenyl-Ether delivers sharp peak shapes, excellent reproducibility, and reliable retention under a wide range of chromatographic conditions. It is particularly suited for analytes where subtle differences in aromatic substitution or polarity must be resolved with precision.
ReproSil Star Phenyl-Ether combines aromatic selectivity with polar interaction capability – the dependable choice for precise and reproducible HPLC separations in pharmaceutical and biotechnical analysis.
