Abstract

A low pressure laser-excited-fluorescence technique (FAGE) for the direct determination of atmospheric NO2 has been developed. Using a frequency-doubled Nd-YAG pump laser and a signal collection time of 20 s (10 s each signal and background) a detection limit of 450 pptv is calculated under laboratory conditions. Improved sensitivities will be possible with a higher repetition rate laser and lower fluorescence cell pressures.
