For normal phase chromatography (HPLC), the ZORBAX NH2 offers a choice of bonded and non-bonded silica packings.

• 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
• To compare technical information and specifications for different phases, see our phase specifications chart

For normal-phase chromatography, the ZORBAX product line offers a choice of bonded and non-bonded silica packings. The ZORBAX CN is a polar bonded-phase column packing used for normal or reversed-phase high performance liquid chromatography, and is less prone to fouling than silica. The ZORBAX CN can be used for separations of compounds ranging from low to high polarity and is often utilized to separate compounds that have been separated on silica columns in the past.

ZORBAX Carbohydrate Analysis Columns are reproducible, efficient, and flexible. These columns use ZORBAX porous silica microsphere technology. Silica manufacture, bonding and packing are all performed in our ISO 9001 facilities. ZORBAX Carbohydrate Analysis Columns can handle high volume injections as much as 50 µl in a 4.6×150 mm column.

Agilent Prep LC Columns are designed for high loadability to purify milligram to gram quantities of products. Column dimensions are available for most preparative sample types ranging from high throughput samples generated in drug discovery to lab scale prep and up to some pilot scale sample preparation. Preparative sized columns are available in 21.2, 30 and 50 mm internal diameters with lengths ranging from 50 to 250 mm. Columns are available in 5 and 10 µm particle sizes with very high efficiency in every dimension.
