The chromatographic impulse response technique with the curve fitting method is a useful tool to measure binary diffusion coefficient under supercritical conditions. Based on our recent measurement data, the effectiveness of the simple predictive correlations such as the D 12 -viscosity correlation and the Schmidt number correlation is presented. Moreover, the sensitivities of the parameters determined and sources of experimental error are discussed. [impulse response, chromatography,
