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.
These columns should be used with non-aqueous mobile phases only.
SUPELCOSIL LC-NH2-NP es una fase amino para cromatografía en fase normal. Al emplear una tecnología especial de enlace, y evitando el agua en su fabricación y prueba de la columna, nosotros hemos reducido considerablemente la variación en la retención que es característica en la cromatografía de fase normal.
