For monitoring of hazardous organic compounds, we have been developing an on-line analytical instrument based on a supersonic jet resonance enhanced multi-photon ionization (Jet-REMPI) mass spectrometry. We have attempted to apply this technique to monitor transient attitudes of hazardous organic compounds in the exhaust gas. It has become possible that the real time monitoring of the gaseous compounds in the atmosphere by our instrument with a continuous sample introduction. We demonstrated that the signals of monochlorobenzene in the chimney could be detected. And the delay time between the gas emission and the gas detection through the 23 m long stainless steel pipe kept 200 °C was 150 seconds. It has been proved that the molecules monitored were well cooled as the result of REMPI spectra. It is greatly advantageous for the selective detection of a specific molecular species.
