Inverse gas chromatography - a different approach to characterization of solids and liquids : ¢review

IGC has become powerful technique in evaluating the properties of solids and liquids. It provides access to several physico-chemical properties of such materials including their surface energy, phase transitions, crystallinity and acid-base characteristics. Kinetic parameters such as diffusion coefficients can be determined. IGC is used to characterize a wide range of product types including pharmaceuticals, natural and synthetic polymers, food ingredients and products, minerals etc. Key words: inverse gas chromatography, acid base interactions, surface free energy
