An analytical solution to Tung's axial dispersion equation. Applications in gel permeation chromatography

摘要

AbstractEquations developed for correctingMn,Mw, and μ for imperfect resolution are generally satisfactory. Choosing the appropriate instrumental spreading function is however a very difcult task. There is need for further research on this problem, in particular with polymer standards for which the DMWD or evenMzis known (in addition toMnandMw).A criterion for resolution in GPC which is based on a solution of Tung's axial dispersion equation has been proposed.The operation of GPC in recycle mode appears very promising. Equations have been developed to interpret data obtained in this operational mode. It is probable that a great deal of work will be done in this area in the very near future
