ION DISSOCIATION IN THE DRIFT TUBE OF A TIME-OFFLIGHT MASS SPECTROMETER: V. ANALYTIC SOLUTIONS OF THE FLIGHT-TIME SHIFT EQUATION,
Abstract
Applying screened trapezoidal potential barriers in the drift tube of a time-of-flight mass spectrometer produces flighttime shifts that can be used to separate and identify products of ion dissociation processes occurring between the ion source and the potential barrier. The flight-time shift is a function of the retarder voltage and mass-to-charge ratios of the fragment and parent ions, expressed by the flight-time shift equation. When the retarder voltage is known, analytic solu tions of this equation allow the retarded ions (fragment or parent) to be identified from the measured flight-time shifts. When the mass-to-charge ratios of these ions are known, similar solutions allow the retarder voltage that will produce a given flight-time shift to be predicted. For part IV see AD-429 438. (Author)
