ZORBAX Original Normal Phase HPLC Columns

For normal-phase chromatography, the Agilent ZORBAX product line offers a choice of bonded and non-bonded silica packings.

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

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

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

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
