Spectra were recorded of all fragment ions formed by elimination of 28-u neutral fragments in fast atom bombardment spectra of peptides in the mass range 1000-1800 u, This approach can provide less complex spectra than either conventionally scanned spectra or product ion scans from collisionaIly activated four-sector experiments, and spectra that contain information that is both overlapping and complementary to those from the other techniques. Constant neutral loss spectra may provide a reading frame for distinguishing sequence ion series in tandem or single analyzer spectra.
