Title

Inverse Gas Chromatography Characterization of Calcium Carbonate

Presenter

Gabriel Crane

Abstract

Using Inverse Gas Chromatography characterization, we can use retention times of known gases to determine both surface and bulk properties of the gas chromatography column filler material calcium carbonate (CaCO3). The main property studied by this method is surface energy, but it can also give information about other properties such as heats of sorption and adsorption isotherms. Carbonates are commonly used in a number of polymer systems as a functional additive; final properties of the polymer compound depend intrinsically on the interfacial tension between the polymer and the calcium carbonate. The IGC technique provides a measure of the mineral’s surface energy allowing a direct calculation of the work of adhesion between the mineral and the polymer
