Descripción

General description

Las columnas fabricadas a base de sílice SUPELCOSIL LC-NH2 separan monosacáridos, disacáridos y algunos trisacáridos, con un orden de elución generalmente según el aumento de peso molecular. La retención disminuye a medida que se incrementa la proporción de agua:acetonitrilo en la fase móvil. Para más información solicite T397126 (Azúcares en columnas SUPELCOSIL LC-NH2)

The amino column is most often employed for the separation of mono- and disaccharides. As a normal phase application, amino columns have found use in the petroleum industry for class-type separations.
