Fast‐atom bombardment negative‐ion mass spectra of various polar compounds (cyclopeptides, nucleosides, organometallic salts) with a m ‐nitrobenzyl alcohol (NBA) matrix exhibit identical characteristics. First, several ions at high masses allow characterization of the molecular weight. Second, at low masses, only ions characteristic of the NBA matrix are observed.
