Glucose, galactose, and mannose in H(2)O and D(2)O were ionized by an atmospheric pressure chemical ionization (APCI) method. Isotope effects on fragmentation patterns of the monosaccharides were examined by deuterium replacement of the -OH groups to distinguish the isomers with a single mass spectrometer. The most abundant ions were the [M+H(2)O](+)() and [M(D5)+D+D(2)O](+) for using H(2)O and D(2)O as solvent and eluent, respectively. Major fragment ions were the [M-OH](+) and [M-OH-H(2)O… CONTINUE READING
