Abstract

Wereporton the development of a highly sensitive detection system for measuring atmospheric NO 2 by means of a laser-induced fluorescence (LIF) technique at 473   nm using a diode-pumped Nd:YAG laser. A GaN-based laser diode emitting at 410   nm is also used as an alternative fluorescence-excitation source. For laboratory calibrations, standard NO 2 gas is diluted with synthetic air and is introduced into a fluorescence-detection cell. The NO 2 LIF signal is detected by a photomultiplier tube andprocessed by a photon-counting method. The minimum detectable limits of the NO 2 instrument developed have been estimated to be 0.14 ppbv and 0.39 ppbv (parts per billion, 10−9, by volume) in 60 s integration time (signal-to-noise ratio of 2) for 473 and 410   nm excitation systems, respectively. Practical performance of the instrument has been demonstrated by the 24 hour continuous measurements of ambient NO 2 in a suburban area.
