## Abstract The ability to predict diffusion coefficients is important in the design, analysis, and operation of plasmid downstream processing operations such as membrane and fixedβbed chromatography. A correlation is proposed to predict the diffusion coefficient, __D__, of supercoiled plasmid DNA

## Abstract Graphical correlations of binary gas diffusion coefficients are developed based on the HirschfelderβBirdβSpotz diffusion equation and the theorem of corresponding states. A critical diffusion coefficient is defined and is used in turn for a definition of a βreducedβ coefficient. The red
