Agilent ZORBAX SB-Aq Rapid Resolution High Definition Threaded Column is a specially designed column for use with ultra-high performance liquid chromatographs (UHPLCs) such as the Agilent 1290 Infinity LC and can be used up to an operating pressure of 1200 bar. The StableBond Aq packing is made by chemically bonding a reversed-phase proprietary alkyl group to a specially prepared, high-purity Agilent ZORBAX porous silica microsphere. The special ZORBAX silica support is designed to reduce or eliminate strong adsorption of basic compounds. The densely covered, sterically protected stationary phase is chemically stable and gives longer column life. As a result, Agilent ZORBAX SB-Aq is a stable, reversed-phase packing that can be used for basic, neutral, or acidic samples. It is particularly well-suited for use with aggressive mobile phases (for example, pH < 2, high ionic strength, ion-pair additives) since the steric protection of the bonded phase resists degradation caused by such mobile phases. This material has also been shown to be stable when operated at temperatures up to 80 °C. These characteristics are particularly important for use in methods that need long-term stability and reproducibility. ZORBAX SB-Aq is especially suited in applications that use high-sensitivity detectors that require low backgrounds (for example, mass spectrometers).
