REMPI (Resonance Enhanced Multi-Photon Ionization) mass spectrometer systems are known for high selectivity, good on-line capabilities, and sensitivities to about 1 ppbv. In this paper, the authors present new data showing DLR Jet -RMPI measurements of tri- and tetra-chlorinated dibenzodioxins. The authors believe these are the first data of their kind, and note their significance in demonstrating that single-color (1 wavelength) Jet-REMPI can measure PCDD congeners at this level of chlorination. The current instrument sensitivity is in the low (60) pptv region, and further work will focus on improving sensitivity by at least 1 or 2 orders of magnitude.
