Inverse Gas Chromatography (IGC) analysis services and applications

By ADSCIENTIS

Physicochemical Analysis of Surface and Material interactivity by Molecular Probes. Solves common questionings like: Same specifications but behave differently, why? What are the impacts of the grinding method, chemical treatment, heat treatment on my samples? Are my powders stable over time and if not, what has changed? What are the effects of a change in the manufacturing process on my product? Measured properties and featured capabilities: Thermodynamic adsorption energies and entropy (∆Ga, ∆Ha and ∆Sa); Polar contribution to the adsorption energy (∆Ga sp =ISP and ∆Ha sp); Nanoroughness and soft matter detection (amorphous) and assessment; Surface energy; Acid-base character (Gutmann concept); Desorption isotherms and irreversible adsorbed probe amounts; Specific surface area determination using any molecular probe including water; Surface heterogeneity tuning thanks to Adsorption Energy Distribution Functions (AEDF); Hansen Solubility Parameter; Probe's diffusion coefficient; Tg and transition points. IGC is a unique technique that delivers numerous physicochemical parameters. Is molecular level sensitive. Varying and multiplying the molecular probe's structure and chemical functions leads to a fine characterization of several aspects involved in your sample interaction ability. The Adscientis team is always available to provide technical support for your instrument, and scientifific expertise to assist with your most challenging applications. Over 20 years of IGC expertise at your service and over 400 IGC measurements per year. Specific measurement protocol development. Free software up-dates. The behaviour of powders, fibres, plates, films and liquids in application are directly related to their interaction ability. Therefore, it is so important to measure it. NeuronIC is a unique solution to do it.
