Collision activated dissociation mass spectrometry of (M+1)(1+) ions from 33 organosulfur compounds are presented.Ions resulting from loss of the radical HS. are prominent in the spectra of thiophenols, dithienyls, trithienyls, and dibenzothiophene derivatives but not in the spectra of aliphatic sulfides or highly alkylated thiophenes.Use of 33 amu neutral loss scans on a triple quadrupole mass spectrometer for the analysis of organosulfur compounds in crude petroleum distillates is described.Total time per sample for this analysis is under 20 min.Qualitative differences in the spectra of several crude oil samples are readily apparent.Preliminary results from collision activated dissociation of (M+NO)(1+) ions in the nitric oxide chemical ionization mass spectra of aliphatic sulfones are described.
