| 中文摘要 | procedures that allow the realization of resonance electron capture (rec) mode on a commercial triple-quadrupole mass spectrometer, after some simple modifications, are described, rec mass spectrometry (ms) and tandem mass spectrometry (ms/ms) experiments were performed and spectra for some compounds were recorded. in particular, the charge-remote fragmentation (crf) spectra of [m - h](-) ions of docosanoic and docosenoic acids under low-energy collisionally activated dissociation (cad) conditions were obtained, and showed that there were no significant differences for [m - h](-) ions produced at different resonances (i,e. for [m - h](-) ions with different structures). this observation was explained on the basis of results obtained from deuterium-labeled fatty acids, which showed that different crf ions (but with the same m/z value in the absence of labels) could be produced by different mechanisms, and all of them were obviously realized under cad conditions that made spectra practically indistinguishable. the other example, which compared the rec-ms/ms spectrum of [m - h](-) ions and ei-ms/ms spectrum of m+. ions of daidzein, demonstrated the potential of the rec-ms/ms technique for more complex structure elucidation. copyright (c) 2000 john wiley & sons, ltd. |
