“…For example, a mixture of DCBz isomers could be selectively detected by measuring the REMPI spectrum. 58 On the other hand, we were able to assign the production as DD and DF generated from a sample of o-CPh by each resonance wavelength, as well as the mass weight. 59 Furthermore, it was possible to obtain a REMPI spectrum of DCDDs generated from a precursor, i.e., 2,4-DCPh, in real-time.…”

We have developed a photon accumulated laser mass spectrometer that enables us to identify isomers of polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran. This system is comprised of a high temperature ͑230°C͒ pulsed gas injector ͑PGI͒, multimirror multipath system ͑MMS͒, and the conventional time-of-flight mass spectrometer. The PGI induces the formation of a choked supersonic jet gas pulse that cools down to a temperature to restrain fragmentation and reduces vibrational and rotational thermal noises. The results suggest that the excited lifetime numbers and fragment dynamics of these species change completely with jet cooling of molecules. The MMS enhances the soft ionization efficiency ͑by a factor of 1000 over a single path system͒ through photon accumulation by extending the irradiation duration ͑to about 40 ns͒ and volume, and it further minimizes fragmentation by carefully controlling the laser intensity distribution within the ionization volume. For the typical isomer 2,3,4,7,8-pentachlorodibenzofuran, the system achieved a detection threshold ͑S/N ratio= 3͒ of 410 ppq ͑equivalent to 4.4 ng/ N m 3 ͒.
