Abstract
We report on the development of a low-cost and compact instrument for quantifying atmospheric concentrations by detecting fluorescence using a commercial light-emitting diode around as a fluorescence excitation light source. The minimum detectable limit of the instrument developed has been estimated to be 9.8 parts per billion of volume mixing ratio (ppbv) in a integration time and with a signal-to-noise ratio of 2.
