General description

An amino phase dedicated to normal-phase chromatography. By employing special bonding technology, and avoiding water in manufacturing and testing the column, we have dramatically reduced the retention variation that is characteristic of normal-phase chromatography. Normal-phase chromatography is especially useful when the analytes are not water soluble -- for example, the fat-soluble vitamins A, D, E, and K.

These columns should be used with non-aqueous mobile phases only.

Features and Benefits

• show stable retention in normal-phase separations
• are less sensitive to small or varying amounts of water in mobile phases, relative to unmodified silica
• provide excellent separations of fat-soluble vitamins
