A variable‐angle tandem mass spectrometer designed and constructed in order to perform angle‐resolved energy distribution experiments required for the investigation of ion–molecule reaction mechanisms is described. The performance of the instrument was tested using the CH~4~^+^–CH~4~ system.

The collision-induced dissociation, (CID) mass spectra of 11 common s-triazine herbicides were investigated using gas chromatography/tandem mass spectrometry on an ion trap mass spectrometer with a temperatureprogrammable injector. The precursor ions of the CID mass spectra studied included both the

Collision lifetimes Tc have been calculated numerically for ion-molecule colliaons. Dipoles cause multiple reflections leading to Tc values much ionger than specular reflection periods. Langevin collisions yield simple specuIar reflections. The interaction has besn studied via a computer-plotter sys
## Abstract Ion/molecule reactions were explored in a newly developed miniature mass spectrometer fitted with a rectilinear ion trap (RIT) mass analyzer. The tandem mass spectrometry performance of this instrument is demonstrated using collision induced dissociation (CID) and ion/molecule reactions
