Development of Supersonic Jet-Resonance Enhanced Multi-photon Ionization Instrument for the Detection of Hazardous Organic Compounds
Nippon steel technical report. Overseas(2011)
摘要
For monitoring of hazardous organic compounds, we have been developing an on-line analytical instrument based on a supersonic jet resonance enhanced multiphoton ionization (Jet-REMPI) mass spectrometry. We have attempted to apply this technique to monitor transient emission phenomena of hazardous organic compounds in the exhaust gas. The real time monitoring of the gaseous compounds in the atmosphere could be done by our instrument with a continuous sample introduction. We demonstrated the emission phenomena of monochlorobenzene generated from the chimney could be monitored every 10 seconds with below 100 ppt concentration level. This technique was proven to become pretreatment-free and high sensitivity analysis for hazardous organic compounds.
