Inverse Gas Chromatography (iGC) can be used to determine the surface properties of many materials. In some cases, as well as surface adsorption, there is also bulk sorption of the iGC probe molecules, allowing bulk materials properties to also be determined. Presented by Prof. Daryl Williams, the webinar presented the use of iGC technique for determining the Tg of polymeric materials and Tg of polymer coatings when applied to highly crystalline fibres, such as fibre sizing and coatings.
