ZORBAX Reversed-Phase Columns | Agilent (1)

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.

Product Details


  • 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

          PFAS Analysis in Milk, Infant Formula, and Related Ingredients Using HPLC

          Per- and polyfluoroalkyl substances (PFAS) are a large group of anthropogenic chemicals that have been applied in industrial, commercial, and domestic products since the 1950s. Because of their toxicity, persistence, and bioaccumulation potential, PFAS have become global environmental pollutants. Besides the environment, the food chain represents another source of exposure, and the risk related to the presence of PFAS in foods has become of increased interest. Whole milk, infant formula, and ingredients used in infant formula production represent important foodstuffs that require sensitive methods with reporting limits at low parts per billion levels or lower for multiple PFAS. This article summarizes optimization experiments and validation of a complete workflow, including sample preparation and a liquid chromatography–tandem mass spectrometry (LC–MS/MS) method for determination of sixteen priority PFAS analytes listed by the U.S. Food and Drug Administration (FDA).
