Agilent, 683975-902, InfinityLab Poroshell 120 SB-C18, 4.6 x 150 mm, 2.7 µm

InfinityLab Poroshell 120 SB-C18, 4.6 x 150 mm, 2.7 µm is used for reversed-phase HPLC and UHPLC separations that benefit from a sterically protected C18 phase and superficially porous particle technology. The column contains 2.7 µm superficially porous particles with a 120 Å pore size and an SB-C18 bonded phase. Its 4.6 mm inner diameter and 150 mm length provide a familiar analytical format while the 600 bar pressure rating supports higher-pressure workflows. The phase has a 7.5% carbon load and is not endcapped. It is designed for strong chemical stability, particularly under low-pH conditions, and supports a pH range of 1–8. The maximum temperature is 90 °C at pH 1–6 and 40 °C at pH 6–8. These operating limits make the column especially useful for methods that use aggressive acidic mobile phases or need stable C18 selectivity under low-pH conditions. It is suitable for both HPLC and UHPLC platforms and is also associated with EPA 8315A applications. The column is shipped in acetonitrile/water and provides a robust option for high-efficiency reversed-phase method development and routine analysis.
