Show Frequency spectrum of LIF gas flame, exhaust O~~--------~------------~ 0.2D~ >0.10 0.00 --> CD 02 '0 ~ 0.0 0.1 0.2 0.3 0.4 :: Hz a E 0.1 cu 2 3 frequency Conclusions • aromatic compound concentrations correlate better with the L1F measurements, • LIF has lower detection limit than CO, • PAC (UF) measurement Is fast and In situ, • L1F provides basis for feedback control • L1F can be used for characterizing formation and decay of PACs, • understanding of the mechanisms of formation and destruction of PAC and other hazardous air pollutants provides basis for determining the strategy of abatement ~ O.
