Adduct ions of monosaccharide molecules with alkali halide triple ions were analyzed by Fast Atom Bombardment (FAB) and Collisionally Activated Dissociation (CAD) techniques. The adduct ions generally appeared in the form of [S+AiXAj]+, where S=monosaccharide molecule, Ai+=Na+, Aj+=Cs+, and X-=Cl-, respectively. First, in FABMS spectra, (AiXAj)+ adduct monosaccharide molecule ions were identified; second, from the mass spectra, the precursor ions were selected, and it was possible to verify their product ions in the CAD spectra. Then, the relative intensities of the product ions were compared. In the present paper, we report the fragmentation processes of [S+AiXAj]+, the main (AiXAj)+, Ai+, Aj+, (S+Ai)+, (S+Aj)+ product ions, the relative intensities of these product ions, and try to explain the interactions occurring in [S+AiXAj]+ adduct ions.
