| Abstract | BIOSIS COPYRIGHT: BIOL ABS. A procedure for the simultaneous identification of seventy-three primary and secondary aromatic amines (including alkyl-, chloro- and nitro-substituted anilines, benzidines, aminonaphthalenes and aminobiphenyls) is described. The amines were derivatized by reaction with heptafluorobutyric anhydride to form the corresponding heptafluorobutyramides. The electrophoric derivatives were analyzed by gas chromatography combined with electron-capture negative-ion chemical ionization mass spectrometry. Linearity was satisfactory for all the compounds examined. Detection limits were in the range 0.3-66.3 pg injected in the full-scan acquisition mode and 0.01-0.57 pg injected in the selected ion monitoring acquisition mode. Application of the procedure to contaminated groundwater samples was also attempted. |
