SURFACE MEASUREMENT SYSTEMS SEA - SURFACE ENERGY ANALYZER
Surface Free Energy - Surface Energy Analyzer - iGC
Brand: SURFACE MEASUREMENT SYSTEMS Product: SEA - SURFACE ENERGY ANALYZER
The New Surface Energy Analyzer (SEA) was developed utilizing the knowledge gained from over 10 years of experience with Inverse Gas Chromatography technology and applications. iGC is a gas-phase technique for characterizing surface and bulk properties of powders, particulates, fibers, films and semi-solids. An experiment consists of a series of vapor pulses or frontal injections eluting through a column packed with the sample under examination. The vapor's retention time is measured by a Flame Ionization Detector (FID). Varying the vapor probe molecule, flow rate, temperature, or column conditions elucidates a wide range of surface and bulk properties of the sample. The SURFACE ENERGY ANALYZER (SEA) represents a huge advance in iGC Technology! The heart of the SEA's innovation is its unique injection manifold system (Patented), which generates solvent pulse sizes of the greatest precision and range accurately producing isotherms at unprecedentedly high and low sample surface coverages. This allows for the accurate determination of surface energy heterogeneity distributions.
