ZORBAX Normal Phase Columns
For normal-phase chromatography, the Agilent ZORBAX product line offers a choice of
bonded and non-bonded silica packings.
ZORBAX Rx-SIL
• Made from highly pure (>99.995%) porous silica microspheres (pore size is the space
between the solid silica microparticles)
• Available in 1.8 and 5 µm particle sizes
• Stronger than other silica types
• Less acidic than ZORBAX-SIL, lower metal content
• Low acidity and low metal content make ZORBAX Rx-SIL ideal for normal-phase separation
of polar compounds that exhibit poor peak symmetry on more acidic silica
• Useful for very hydrophilic compounds with high organic mobile phases in HILIC mode
ZORBAX Eclipse XDB-CN
• Made from highly pure Rx-SIL
• Excellent choice for normal phase applications with basic compounds
• Equilibrates more rapidly than ZORBAX Rx-SIL and is used for many of the same
normal-phase applications
ZORBAX CN
• Cyanopropyldimethylsilane monolayer bonded to ZORBAX SIL
• Equilibrates more rapidly than ZORBAX SIL, and used for many of the same normal-phase
applications
• Less prone to fouling and less water sensitive than silica

ZORBAX Normal Phase Columns
• Amino-propyl silane phase bonded to ZORBAX SIL
• Used for normal phase and weak anion-exchange, and reversed-phase HPLC
of polar compounds
• Vitamins A and D are separated in the normal-phase mode
• Carbohydrates and sugars are separated in the reversed-phase mode
