Abstract:

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.
