Surface Measurement Systems Inverse Gas Chromatography-Surface Energy Analyser (iGC-SEA)

The Inverse Gas Chromatography-Surface Energy Analyser (iGC-SEA) is part of the Surface Measurement Systems UK (SMS) product range of dynamic vapour sorption (DVS) technology and inverse gas chromatography instrumentation and solutions.

The system is specially designed to determine the surface energy heterogeneity in many applications. Suitable for measuring different surface and bulk properties of solid materials, it can be used for characterising particles and powders, nanomaterials, films, fibres, composites and bulk solids.

The second-generation inverse gas chromatography instrument is based on the IGC principle. The SMS injection scheme provides a wide range of injection concentrations with good reproducibility. Data includes acid/base properties, heat of sorption, glass transition temperature and solubility parameters.

The system features fully automated operation with comprehensive data analysis software, which is wizard based. It also includes up to 12 different probe gas molecules, optional humidity control and in situ sample pre-conditioning.
