			The SEA is based on Inverse Gas Chromatography (IGC) methodology and is a gas phase technique for characterising surface and bulk properties of solid materials. The principles of IGC are very simple, being the reverse of a conventional gas chromatographic (GC) experiment.
			A cylindrical column is uniformly packed with the solid material of interest, typically a powder, fibre or film. A pulse or constant concentration of gas is then injected down the column at a fixed carrier gas flow rate , and the time taken for the pulse or concentration front to elute down the column is measured by a detector. A series of IGC measurements with different gas phase probe molecules then allows access to a wide range of phyisco-chemical properties of the solid sample.
