Surface Energy Analyzer

The iGC Surface Energy Analyzer (SEA) continues Surface Measurement Systems? pioneering history with inverse gas chromatography (IGC), which now spans more than fifteen years.

The SEA is a second generation Inverse Gas Chromatograph instrument. The revolutionary SEA is the world?s only commercial instrument based on the ICG principle. The unique SMS injection scheme provides a wide range of injection concentrations with unrivalled accuracy and reproducibility.
How does the Surface Energy Anlayzer (SEA) work?

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 of 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.
