“…Photo-induced dissociation (PID) as a means of inducing the fragmentation of ions has been used with several types of mass spectrometers. McGilvery and Morrison [1] and Krailler and Russell [2,3] have directed the laser beam perpendicularly to the low density ion beam in the interaction region of, respectively, quadrupole and sector mass spectrometers. The low sensitivity with orthogonal excitation they observed was improved by the use of a coaxial geometry which placed a greater number of ions in the laser beam.…”

High efficiency photo-induced dissociation (PID) has been demonstrated in a tandem time-of-flight mass spectrometer. This instrument focuses isomass ion packets to temporal and spatial dimensions similar to those of the focused laser pulses from a high power excimer laser. This high density overlap of photons and ions yields highly efficient fragmentation and also provides high resolution selection of specific precursor ion mass-to-charge ratio values. Using 193 nm photon excitation of the molecular ion of bromobenzene (m/z = 1561, fragmentation, collection, and PID efficiencies af 79%, 132%, and 104%, respectively, were obtained. Characteristic fragmentations of toluene, nitrobenzene, acetophenone, triethylamine, N,N-diethylformamide, N-methylacetamide, and cyclohexene have also been demonstrated.
