Abstract: A laser-based ultra-sensitive detection technique used for determining urban air pollutants caused by car exhaust has been described.Asmall ion chamber working under the condition of atmospheric pressure was used as the detector and a laser system with UVoutput was used as the light source.A 1 + 1 and a 2 + 1 REMPI scheme were used for the ultra-sensitive analysis of NOx(x=1 ,2) and COin car exhaust.

Key words: Ultra-sensitive detection, Air pollutant caused by car exhaust, Resonant enhanced multi-pho-tonionization(REMPI)
