iGC- SEA or Inverse Gas Chromatography-Surface Energy Analyzer is an instrument that uses the iGC principle. The heart of its innovation is the patented injection manifold system which generates accurate solvent pulse sizes across a large concentration range, resulting in isotherms at unprecedented high and low sample surface coverages. This allows for the accurate determination of surface energy heterogeneity distributions. The fully automated iGC-SEA can be operated at different solvent vapor, flow rate, temperature, humidity and column conditions.

iGC-SEA has a unique data analysis software called Cirrus Plus, specifically designed to measure surface energy heterogeneity, isotherm properties and related physical characterization parameters. Further, bulk solid property experiments resulting from probe-bulk interaction and using solubility theory are now possible. It automatically and directly provides a wide range of surface and bulk properties of the solid samples and gives more accurate and reliable data than manual calculations. It also has a humidity control option. The impact of humidity and temperature can be determined for the physicochemical properties of solids such as as moisture induced Tg, BET specific surface area, surface energy, wettability, adhesion and cohesion.

Dynamic Vapor Sorption
Price on request

Dynamic Vapor Sorption (DVS) is a gravimetric technique that measures how quickly and how much of a solvent is absorbed by a sample: such as a dry powder absorbing water. It does this by varying the vapor concentration surrounding the sample and measuring the change in mass which this produces. Water vapor is most commonly used,... Show more »

Dynamic Vapor Sorption (DVS) is a gravimetric technique that measures how quickly and how much of a solvent is absorbed by a sample: such as a dry powder absorbing water. It does this by varying the vapor concentration surrounding the sample and measuring the change in mass which this produces. Water vapor is most commonly used, but it is also possible to use a wide range of organic solvents.

Dynamic Vapor Sorption is a valued tool in laboratories all over the world, within R&D, from polymorphism and compound stability studies to bulk and surface sorption effects of water and organic vapours. It is a vital part of quality control analysis techniques for both scale-up and production, and can even be found within the packaging area, measuring efficacy, permeability, and the effects of humidity and temperature on the samples within the packaging.
