일반 설명
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.
