The voltage pulsing of the collision cell on a mass‐analysed ion kinetic energy spectrometer allows simultaneous kinetic energy release measurements for unimolecular ( T ( V )), collision‐induced ( T CID ( V )) and composite unimolecular and collision‐induced ( T comp ( V )) decomposition processes in the time frame of a capillary gas chromatographic peak. The information gained by voltage pulsing sometimes allows more reliable isomer identification than by kinetic energy release measurements made in the non‐pulsing mode alone. Presented are T ( V ), T CID ( V ) and T comp ( V ), and the ratio of their intensities for a number of isomeric halogenated compounds.
