Oligopeptides subjected to partial enzyme hydrolysis provide mixtures of sub-peptides which optimize amino acid sequence determination by fast atom bombardment mass spectrometry. The digestion mixture can be sampled directly; there is no interference from the enzyme. Complete sequences were obtained
The fast atom bombardment (FAB) mass spectra and low-energy collisional activation mass spectra of ions generated under FAB were investigated for twelve bisbenzylisoquinoline (BBI) alkaloids. The relative molecular mass of the free base and diquaternary BBI alkaloids can be obtained from FAB data. H
