Answer:A phenyl bonded phase adds aromatic π–π interactions to reversed-phase retention.
Answer:250 × 4.6 mm column packed with 5 µm, 120 Å phenyl silica.
Answer:Approximately pH 2.0 to 7.5.
The YMC-Pack Ph column offers phenyl bonded reversed-phase selectivity for analytes whose aromatic structures interact with the stationary phase. Unlike alkyl-only phases, the phenyl functionality can provide π–π interactions in addition to hydrophobic retention, making it an alternative for aromatic compounds, phenols, sweeteners and selected peptide separations. This analytical column uses fully endcapped, monomerically bonded phenyl silica with 120 Å pores and 5 µm particles in a 250 × 4.6 mm format. The longer bed provides separation capacity for methods needing additional theoretical plates, with a corresponding increase in analysis time and pressure relative to shorter formats. Select mobile-phase organic content and buffer conditions to balance aromatic selectivity, retention and peak shape. Maintain operation within the recommended pH range of 2–7.5 and verify temperature compatibility for the method. Filter solutions, avoid strongly precipitating sample solvents and protect the column from contamination. The supplied article is a complete analytical phenyl column rather than a C18 column or replacement cartridge.
