Surface-Induced Dissociation in Tandem Quadrupole Mass Spectrometers: AComparison of Three Designs

摘要

Three different devices that can be used for surface-induced dissociation intandem quadrupole instruments are compared here. The designs were compared by examining the fragmentation + of several compounds including benzene, W(CO)6, and (CH3)4N+. These studies show that SID can be readily implemented on a variety of tandem quadrupole instruments and that the spectra obtained with the in-line and 90 0 instruments are similar. Evidence is presented that confirms that high average internal energies and narrow distributions of internal energy are available by this technique. Efficiencies for fragmentation of odd-electron ions are on the order of those previously reported by Cooks et al. The overall SID efficiency for even-electron ions is higher than that for odd-electron ions of similar structure.
