CHARGE TRANSFER STUDIES WITH A TIME-OF-FLIGHT MASS SPECTROMETER: II. KINETIC ANALYSIS, INCLUDING ATTENUATION OF BOTH NEUTRALS AND IONS BY SCATTERING,

Pagination or Media Count:
The kinetics of charge transfer processes that occur in the drift tube of a time-of-flight mass spectrometer are analyzed, with due regard to attenuation of both ions and neutrals by scattering. The same equation that expresses the charge transfer cross section in terms of experimentally measurable quantities provides for independent determination, from the same experimental measurements, of the difference between the total scattering cross section for the neutrals and that for the ions involved in the charge transfer process being studied. A second, and much simpler, equation for the charge transfer cross section is used when the scattering cross sections for neutrals and ions are the same. Both equations allow for differences in detector response to neutrals compared with that to ions. Author
