Observation and Identification of Ion Dissociation Processes Occurring in the Drift Tube of a Time-of-flight Mass Spectrometer
註釋The shifts in ion flight times produced by a flat-top potential barrier applied within the drift tube of a time-of-flight mass spectrometer are defined analytically in terms of the height of the potential barrier. These flight-time shifts are selectively dependent on the mass, charge, and kinetic energy of the ions involved; consequently, they can be used to spearate and identify the products of ion dissociation processes occurring in the drift tube. Comparisons of calculated and observed flight-time shifts for the 58 + to 43+, 42+ dissociations in n-butane are used to illustrate the applicability and present limitations of this method of identifying dissociation products.
