Description:
Jet REMPI-TOFMS is a measurement technique which combines laser induced photoionization with mass spectrometry to create a two-dimensional (wavelength / mass) detection method. In combination with a supersonic jet inlet, aromatic organics are detected in real time (one data point per second) at concentration levels as low as 100 PPT with high selectivity and isomer-specific sensitivity. In this field test, jet REMPI-TOFMS was used to monitor real time polycyclic aromatic hydrocarbons and monochlorobenzene as present in the flue gas of a municipal waste incinerator. Experimental results were obtained during several incinerator conditions such as steady state operation, scheduled shutdowns, startups and periods of poor combustion.
