Agilent ZORBAX Eclipse XDB columns – C18, C8, Phenyl and CN – provide four bonded phase choices for method development optimization. These columns provide good peak shape over a wide pH range (2–9) for additional method development flexibility with one family of columns. Eclipse XDB columns can be used for method development at low pH (2–3) and the same column can be used for method development in the mid pH (6–8) region. In the mid pH region, residual silanols are more active and tailing interactions are more likely. To overcome these interactions, Eclipse XDB columns are extra densely bonded and double endcapped through a proprietary process to cover as many active silanols as possible. The result is superior peak shape of basic compounds from pH 2–9. 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.

Features
    Four selectivity choices for method development optimization
    Good peak shape for basic, acidic and neutral compounds
    High performance over a wide pH range – pH 2–9
    Particle sizes from 1.8 to 7 μm
    Long lifetime with extra dense bonding (XDB) and double endcapping
    Eclipse XDB-CN equilibrates more rapidly than ZORBAX Rx-Sil and is used for many of the same normal-phase applications

Specifications
Eclipse XDB columns can be used for initial method development at low pH (2–3) and will provide high resolution and excellent peak shape of all types of compounds. The same column can be used for method development in the mid pH (6–8) region. In the mid pH region residual silanols are more active and tailing interactions are more likely. To overcome these interactions, Eclipse XDB columns are extra densely bonded and double endcapped through a proprietary process to cover as many active silanols at possible. The result is superior peak shape of basic compounds from pH 2 9.

Eclipse XDB columns are available in C18, C8, Phenyl and CN bonded phases for selectivity optimization of most separations with StableBond, Bonus-RP and Extend-C18 available as additional selectivity choices. Eclipse XDB columns are available in particle sizes ranging from 1.8 µm to 7 µm RRHT to Prep. Rapid Resolution HT (RRHT) columns provide the fastest analysis times and the highest resolution in a new wider range of column dimensions supporting high-pressure use.
