M. Moeckli et Mw. Sigrist, FIELD MONITORING OF TRAFFIC-RELEASED POLLUTANTS WITH MOBILE PHOTOACOUSTIC SYSTEM, Progress in Natural Science, 6, 1996, pp. 622-625
A mobile photoacoustic trace gas detection system based on a CO2 laser
and a resonant absorption cell was applied to the study of traffic em
itted pollutants al a freeway tunnel in Switzerland. The main results
are presented, including a new approach in the analysis of photoacoust
ic absorption spectra.
