The Agilent ZORBAX Eclipse XDB-CN (part number 990967-905) is a 4.6 x 250 mm, 5 µm fully porous HPLC analytical column with a cyano (CN) bonded phase. It is designed to retain and separate polar and mid‑polar compounds in reversed‑phase mode and can be converted for normal‑phase use after appropriate solvent flushing. Typical uses include method development and routine HPLC analyses that require improved peak shape for polar analytes.
Key Features:
- Column dimensions: 4.6 mm ID x 250 mm length
- Particle size: 5 µm (fully porous)
- Phase/chemistry: Eclipse XDB‑CN (cyano bonded phase, XDB)
- Pore size: 80 Å
- USP designation: L10
- pH range: 2–9
- Maximum pressure rating: 400 bar
Advantages:
- eXtra Densely Bonded (XDB) chemistry and double endcapping reduce active silanol interactions, giving improved peak shape and reproducibility for polar analytes.
- Versatile selectivity: optimized for retaining polar and mid‑polar compounds in reversed phase but can be used in normal phase after flushing, aiding method development.
- Robust operating window (pH 2–9 and 400 bar rating) supports routine analytical workflows and reliable lifetime under common HPLC conditions.
