N2 - A laser desorption time-of-flight (LD-TOF) mass spectrometer has been used to study the time-resolved desorption of nonvolatile organic salts following a laser pulse. An electron beam, pulsed prior to the pulse which draws the ions from the source, can be used to examine the neutral species desorbed by the laser. Experiments on tetraalkylammonium halides indicate desorption rates for neutral decomposition products vastly different from those for intact ions and neutral clusters, so that the method can be used to resolve competing thermal processes.
