In this study a mechanistic model for chromatography was taken and the solution to its Laplace transfer function was obtained using the Fast Fourier Transform method. Using previously developed correlations for modelling diffusion, both in solution a

The phase behavior effect on the kinetics of transesterification reactions is investigated in this study. First, the partition coefficient of the catalyst, KOH, was determined. It was found that the vast majority of the catalyst resides in the methan

Centrifugal precipitation chromatography (CPC) is a separation system that mainly employs a moving concentration gradient of precipitating agent along a channel. Solutes of interest undergo repetitive precipitation-dissolution, and fractionate at dif
