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.
