Abstract

CO-laser based photoacoustic detection of nitric oxide has been experimentally investigated and modeled. Using a model based on relaxation rate equations of the species present, the influence of H₂O vapor on NO relaxation was determined. This can help explain the observed amplitude and phase lags of the photoacoustic signal as a function of NO and H₂O concentrations.
