The Effects of Thermal Energy and Ion-Removal Time on the "Pulsed Source" Method for Mass Spectrometer Investigations of Ion?Molecule Reactions

Abstract

This paper examines two aspects of an experimental technique designed to investigate the dependence of ion-molecule specific reaction rates on primary ion energy. In this experiment the reaction proceeds in a mass spectrometer ion source under a constant electric field, and the ratio of secondary to primary ions is recorded as a function of time.
