Analysis of pyridylaminated (PA) monosaccharides


Pyridylaminated (PA) monosaccharides were analysed by the Shodex SUGAR series
Asahipak NH2P-50 4E. Carbohydrates
are usually detected by refractive index detector (RI), but pyridylamination
of saccharides enables high sensitivity analysis by fluorescence detector.
