SUPELCOSIL™ LC-NH2-NP HPLC Column
5 μm particle size, L × I.D. 25 cm × 4.6 mm
 
SUPELCOSIL™ HPLC Columns
Traditional HPLC columns, similar to Hypersil™
Our SUPELCOSIL silica-based HPLC column line includes over 40 bonded phase chemistries, in a range of particle sizes and column configurations from microbore to preparative scale. It is the original high quality Supelco product line referenced in many USP methods.
In the case of a few SUPLECOSIL phases, we have recommended alternatives based on more advanced column technology.

SUPELCOSIL LC-NH2-NP columns:

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

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

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.
