The Agilent ZORBAX SB-C18 RRHT Threaded Column is designed for high-pressure operation (up to 600 bar) and is packed with a high-performance microparticulate C18 packing for high-speed reversed phase HPLC. The StableBond packing is made by chemically bonding a sterically-protected C18 stationary phase to a specially prepared, high purity 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, diisobutyl n-octadecylsilane stationary phase is chemically stable and gives longer column life. As a result, ZORBAX SB-C18 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, etc.) 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 90 °C. These characteristics are particularly important for use in methods that need long-term stability and reproducibility. ZORBAX SB-C18 is especially suited in applications that use high-sensitivity detectors that require low backgrounds (for example, mass spectrometers). The uniform, spherical, ZORBAX SB-C18 particles have a controlled pore size of 80Å.
