Agilent ZORBAX SB-CN RRHT Threaded Column Datasheet

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