Time-resolved measurements of volatile organic compounds (VOC) and poly aromatic hydrocarbon (PAH) in exhaust gas from automobiles in a driving mode have been performed using Supersonic Jet / resonance enhanced multi-photon ionization (Jet-REMPI) method with 10 ppb sensitivity. Benzene, naphthalene and phenol were measured before and after catalyst treatment in the diesel cars. At the same time total hydrocarbon (THC) was detected by FID through a CVS instrument, which is the normal method for real-time measurement of hydrocarbon without distinction of hydrocarbon species in exhaust gas. The changes in concentration of benzene and other PAH corresponding to the changes in the driving mode were successfully measured every 1 second. As a result of real-time monitoring of exhaust gas from diesel engine, benzene, naphthalene and phenol were quantified at JE05 mode. Compared a real-time PAH and VOC signals with a total hydrocarbon signal detected by FID, it was found that each tendency of benzene and naphthalene was almost same as that of THC, while the tendency of phenol is different from that of THC.
