Surface Energy Analyzers/Inverse Gas Chromatograph

RSS
Surface energy analyzers or second generation inverse gas chromatographs are used to characterize particulates, fibres and thin-films. It is a gas phase technique used to determine a range of surface and bulk properties. It involves passing a constant concentration of gas through a column of solid material and the time taken for the concentration front to elute down the column is measured with a detector. A variety of physico-chemical properties can be determined by using a range of different gas probe molecules.
