Influence of mass transport and quenching on nitric oxide chemiluminescent analysis

Data indicating the influence of carrier or bulk gases on the calibration of low-pressure chemiluminescent NO analyzers are presented. A theory of instrument performance incorporating both capillary flow theory and quenching theory is developed. The predictions of a model based on this theory are compared with these data and the predictions of quenching theory alone. The limitations of using only quenching theory to predict instrument response for binary mixtures are demonstrated. Data useful for estimating measurement errors are given.
