Abstract

We report on the development of a low-cost and compact instrument for quantifying atmospheric NO 2 concentrations by detecting NO 2 fluorescence using a commercial light-emitting diode around 435 nm as a fluorescence excitation light source. The minimum detectable limit of the NO 2 instrument developed has been estimated to be 9.8 parts per billion of volume mixing ratio (ppbv) in a 60 s integration time and with a signal-to-noise ratio of 2.
