Notizen:
Resonance-enhanced multiphoton ionization has been used to detect the presence of vapour-phase explosive-type samples in a linear time-of-flight (TOF) mass spectrometer. In particular, nitrobenzene, 2-nitrotoluene, 2,4-dinitrotoluene, 2,4,6-trinitrotoluene, ethylene glycol dinitrate, pentaerythritol tetranitrate (PETN), 1,3,5-trinitro-1,3,5-triazacyclohexane (RDX) and SEMTEX (PETN plus RDX plus plasticizer) have been analysed at a laser wavelength of 226.3 nm corresponding to a strong resonant transition of the neutral NO molecule. TOF mass spectra have been recorded and the intensity of the NO+ ion monitored as a function of temperature for comparison with the temperature dependence of the various vapour pressures.
