Notes:
The positive and negative ion fast atom bombardment mass spectra of methyl α-D-galactopyranoside 2-, 3-, 4- and 6-(sodium sulphate) cannot be used for differentiation among the various positional isomers. The metastable ion and collisional activation spectra of the [M + Na]+ as well as the [M - Na]- and [M - H]- ions, however, allow an easy determination of the position of the sulphate group.
