Abstract
To understand the efficiency of separation achievable by different methodologies we ought examine the entropy changes accompanying a process. By appropriate idealization, chromatography and other differential migrations are found to be isoentropic processes. Minimization of the irreversibilities of real, as opposed to ideal, processes leads to highly efficient methods. Because of their isoentropic nature, differential migrations offer the most separation for the least effort.Keywords
