The results of an investigation of ion/molecule reactions in gaseous m
ixtures of ammonia and argon, and pure ammonia are presented. Relative
values of the ion currents for observed ions were determined as a fun
ction of the gas pressure in the ion source collision chamber, and of
the concentration of ammonia in the mixture. The reaction rate constan
ts for NH3+, NH2+ and NH+ ions in pure ammonia were determined. Measur
ements were performed using a mass spectrometer with the high pressure
ion source constructed by the authors.
