Agilent ZORBAX Reversed-Phase Columns

ZORBAX Reversed-Phase Columns

    The ZORBAX column family is one of the most popular high-performance liquid chromatography (HPLC) column families for reversed-phase HPLC. ZORBAX columns are based on traditional fully porous particles and offer the highest loading capacity and resolution. From Eclipse Plus, Eclipse XDB, StableBond, Bonus-RP and more, the ZORBAX column portfolio offers a wide selection of stationary phases allowing you to fine-tune your selectivity to match your application. Improve resolution by utilizing sub-2 µm particles to maximize system efficiency and confidently scale-up to preparative HPLC and/or easy HPLC method transfer.

    Reversed-Phase LC Columns | Liquid Chromatography

    • Traditional, fully porous particles available in 1.8, 3.5, and 5 µm sizes. With selected products also available in 7 μm particles for preparative HPLC (see Prep LC columns section)
    • ZORBAX Eclipse Plus columns are the recommended starting point for method development at mid-pH and benefit from the ultimate performance from fully porous silica-based columns
    • ZORBAX StableBond columns offer the highest stability for low pH applications down to pH 1 while ZORBAX SB-Aq deliver robust, reproducible separations with highly aqueous mobile phases, including 100% water
    • ZORBAX Eclipse XDB columns – C18, C8, Phenyl and CN – provide four bonded phase choices for method development optimization. These columns are eXtra Densely Bonded (XDB) and double endcapped through a proprietary process to cover as many active silanols as possible. Eclipse XDB columns are available in 1.8, 3.5, 5 and 7 μm particle sizes for high speed, high resolution, analytical and prep scale separations
    • ZORBAX Extend-C18 columns offer high efficiency and selectivity advantages for basic compounds in for high pH applications up to pH 11.5
    • ZORBAX Bonus RP columns offer unique selectivity due to an embedded amide linkage in the C14-alkyl chain making them ideal for 100% aqueous mobile phases and for compounds that are not retained on standard reverse phase columns
    • ZORBAX Rx columns are made from highly pure (>99.995 %) porous silica with a higher carbon load (12%)
    • ZORBAX Eclipse PAH columns deliver high resolution separation of the 16 polycyclic aromatic hydrocarbons (PAHs) in EPA 610 and have been specifically tested with PAHs for maximum reproducibility
    • ZORBAX Rapid Resolution High Definition (RRHD) columns are packed with 1.8 μm particles and stable up to 1200 bar for fast, high-resolution separations of your most complex samples
    • ZORBAX Rapid Resolution High Throughput (RRHT) columns use totally porous 1.8 μm particles to provide maximum resolution in ultra-fast and high-resolution analyses with a pressure limit of 600 bar
    • Agilent UHPLC Guards extend the lifetime of analytical columns – without diminishing performance – and use easy-to-install hardware that fits directly on the end of the column
