内容記述 |
Positive ion electron impact (PIEI), positive ion chemical ionization (PICI) and negative ion chemical ionization (NICI) mass spectra are presented for seven dinitroaniline herbicides; and each fragmentation pathway has been analyzed. In the PIEI mode, molecular ions appeared for all compounds, but they were relatively small. Base or intense cations at m/z M-29 , which probably correspond to [M-C2H5] +, appeared in five compounds; [M - OH]+ peaks also observed for six compounds. In the PICI mass spectra, all compounds showed intense MH+ quasi-molecular ions, which constituted base peaks, together with small peaks at m/z M + C2H5 and/or M + C3H5; small peaks at m/z M - 33, which probably correspond to [MH-2OH]+,were observed in six compounds. In the NICI mass spectra, M- molecular anions appeared as base peaks in all compounds. Anions at m/z [M - 30]-, which may be due to loss of NO, were also observed in common for all compounds. The highest sensitivity could be obtained in the NICI mode by total ion monitoring for all compounds. The calibration curves obtained by selected ion monitoring in the NICI mode for isopropalin, nitralin and trifluralin, showed linearity in the range of 1.56-100 pg on column, with detection limits of 2-20 pg on column. |
