Inverse gas chromatography applications in polymer–solvent systems

Inverse gas chromatography (IGC) has been shown by previous efforts to be an efficient and reliable method of obtaining the solubility and diffusion coefficients of solvents in polymers when the solvents are infinitely dilute. We have extended the IGC method to finite concentrations and to multicomponent systems. The experimental procedures have been improved to provide data more efficiently without loss of accuracy.
