Answer:3.9 × 150 mm with 5 µm particles and 125 Å pores.
Answer:Peak shape and selectivity for highly basic analytes in reversed-phase HPLC.
Answer:pH 2–12.
The Waters XTerra Shield RP18 reversed-phase HPLC column uses 5 µm hybrid silica particles with 125 Å pores in a 3.9 × 150 mm analytical column. Embedded polar group chemistry in the Shield RP18 stationary phase reduces unwanted interactions with basic analytes and can improve chromatographic peak shape. The hybrid particle technology supports a working mobile-phase pH range of 2–12, enabling broader method development conditions than many conventional silica-based C18 phases. This endcapped USP L1 column is suitable for pharmaceutical and small-molecule reversed-phase separations where analyte selectivity and base retention are important. The package contains one analytical column.
