High-resolution detection of collision-induced dissociation fragments by Fourier transform mass spectrometry
Results of the application of Nicolet prototype Fourier transform mass spectrometers (FTMS) technique to the study of collision-induced dissociation (CID) of proton-bound alcohol dimers and metal-ion bound alcohol dimers are reported. Sequential CIDs have been observed by operating the instrument in an MS/MS/MS manner to examine the CID of ions that are themselves the result of CID fragmentation. The recorded spectra were all obtained by operating the instrument in the heterodyne mode. The molecular ions of acetone and isopropyl chloride both undergo CID to give isobaric ions of a nominal m/Z 43. However, the fact that the accuracy of the mass measurements of the recorded spectra is somewhat less than had been previously reported may be partly due to a perturbation of the trapping cell electric field due to a modification of the apparatus. It was noted that both resolution and the maximum translational energy that can be imparted to an ion before ejection are inversely proportional to ionic mass.
