A new method to estimate the oxygen transfer coefficient ( K L a ) from the experimental dynamic response data is presented. Employing a linear model which allows for gas phase, diffusion film, and oxygen electrode dynamics, the first moment of the response curve is simply related to the sum of the model parameters. Two separate experiments are used to characterize the measurement dynamics and to measure the unknown K L a parameter. The simple calculation procedure involves only measuring the area above the response curves.
