Notes:
The positive and negative ion fast atom bombardment mass spectra of methyl α-D-mannopyranoside 2-, 3-, 4- and 6-(sodium sulphate) show distinct pseudo-molecular ions. The fragment ions in the mass spectra are insufficiently characteristic to differentiate among the positional isomers. The tandem mass spectra of the [M + Na]+ and [M - Na]- ions, however, are suitable for identification of the position of the sulphate group.
