The influence of the pH, the nature of the matrix and the presence of a surfactant on the positive-and negative-ion abundance in the molecular mass region in the fast atom bombardment (FAB) mass spectra of methyl red was investigated. A small but significant pH effect was observed which was attribut

The collision-induced decomposition mass spectrum of protonated rn-nitrobenzyl alcohol (NBA) was studied. The various cluster ions fragment mainly by loss of neutral NBA. Nitro-to-nitrite isomerization followed by loss of 'NO is a favoured fragmentation pathway of the [MH]+ ion. Eliminations of \*OH
The most intense ion(s) in negative ion fast atom bombardment (FAB) mass spectra of 2-and 4benzaldehyde sulfonic acid (BSA) in glycerol or 3-nitrobenzyl alcohol matrix corresponds to a covalent association of the analyte with one or two matrix molecules accompanied by the elimination of a molecule o
