SEA-iGC

IGC-SEA The Inverse Gas Chromatography-Surface Energy Analyzer or iGC-SEA continues Surface Measurement Systems’ pioneering history with inverse gas chromatography (IGC), which now spans more than fifteen years. The iGC-SEA is a second generation Inverse Gas Chromatography instrument. It is the world’s only commercial instrument based on the IGC principle. The unique SMS injection scheme provides a wide range of injection concentrations with unrivalled accuracy and reproducibility.         The iGC-SEA provides unique access to the following physico-chemical properties of a wide range of solid materials in a controlled humidity environment: Dispersive and polar surface energiesHeats and entropies of adsorptionAcid/base interactionsPhase transitionsSorption isothermsPermeability, solubility and diffusionMicropore and mesopore distributionsCompetetive (Multicomponent) adsorptionSurface energy heterogeneity mapping   Instrument features include:   ·       Unrivalled accuracy and repeatability ·       Fully automated operation ·       Comprehensive data analysis software ·       Up to 12 different probe gas molecules ·       User friendly wizard based software ·       Optional humidity control ·       In-Situ sample pre-conditioning ·       Wide temperature range ·       Column packing accessory
