Surface Energy Analyzers / Inverse Gas Chromatograph

Inverse gas chromatography (IGC) is a non-destructive, sensitive and relatively fast technique available for researchers interested in characterizing the physicochemical properties of a material of interest. Materials to be investigated are placed in the chromatographic column of the IGC, and a known probe vapor is then applied to the sample in order to obtain information regarding the surface properties of the material. The interactions that occur between the applied molecular probes and the investigated material will determine the measured retention times, as well as the shape of the obtained peaks, allowing the determination of numerous physicochemical properties of the material.
