ZORBAX Normal Phase HPLC Columns

By Agilent Technologies

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

Rx-SIL

  • Made from highly pure (>99.995%) porous silica microspheres
  • 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 reversed phase mode

CN

  • Cyanopropyldimethylsilane monolayer bonded to ZORBAX SIL
  • Equilibrates more rapidly than ZORBAX SIL, and is used for many of the same normal-phase applications
  • Less prone to fouling and less water-sensitive than silica

NH2

  • 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 on ZORBAX NH2

Carbohydrate Analysis Columns

  • Reproducible: Each lot of this application's specific aminopropyl column packing material is use-tested for specific monosaccharide and disaccharide separations.
  • Efficient: Uses ZORBAX porous silica microsphere technology. Silica manufacturing, bonding and packing are all performed in ISO9001 facilities.
  • Flexible: Can handle high-volume injections - as much as 50 µL on a 4.6 x 150 mm column.

Particle size 5.0µm, and surface area 300m2/g. Pore size 70 angstrom. pH range 2.0-8.0.
