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
