Resonant ejection of ion species from the quadrupole ion store (QUISTOR) is shown to reveal the coupling of reactant ions with product ions in ion/molecule reactions studied with the QUISTOR – quadrupole mass filter combination. The technique involves the use of selective ejection of a chosen ionic precursor and the simultaneous observation of the perturbations in the concentration of product ions. The technique is demonstrated in studies of the ion chemistry and reaction kinetics of two known chemical systems.
