This paper discusses how the kinetic ion mobility mass spectrometer is used to measure the rate constants of ion-molecule reactions in an atmospheric pressure buffer gas. One operational mode of the instrument avoids measurement errors associated with aperture sampling of a high-pressure ionized gas. This instrument is used to study the S{sub N}2 nucleophilic displacement reactions of chloride anions with a series of alkyl bromides in nitrogen. 40 refs., 13 figs., 2 tabs.
