Abstract

A new atmospheric NO₂ monitor with a detectability of O. 6 ppbv is described. A compact He-Cd 10 mIN 442nm laser excites the NO₂ molecules and the resultant fluorescence was monitored by photon counting over an 80 sec integration time. The high sensitivity was achieved by development of an optimal NO₂ fluorescence bandpass liquid solution filter which did not fluoresce upon absorption of scattered laser light.
