New Smart Surface Analyzer neuronIC Webinar

2020-11-19 Gravite Science

Monday, 30 November 2020,  4.00 - 5.00 pm CET


In a short review, we will review briefly the basics of surface characterization by dynamic gas adsorption using 15 and more different gas probe, also called Inverse Gas Chromatography (IGC). In more depth, we will describe common drawbacks and difficulties of IGC measurements.  We will explain the innovative approach of the new Neuronic instrument including concept as the frontal injection and examples of applications.

A special emphasis will be on the unique determination of isotherms based on a single experiment using the flow injection mode to achieve constant p/p0 and the analysis of the desorption curve. You will learn, how the specific surface area in m2/g can be determined by a BET regression using different gaseous probes (even water vapor) and at room temperature and above. Interpretation of the same desorption curve delivers also the Adsorption Energy Distribution Function (AEDF), a measure of the surface heterogeneity.


The instrumental details as well as operational questions will be part of the presentation and the discussion.
 
Who should attend
This webinar is for physical chemist, researchers, material scientists and application specialists who are practically dealing with the characterization of powders, fibers and even plates – and who are not satisfied with existing solutions.  
 
Why you should participate 
Surface characterization by Inverse Gas Chromatography  (IGC) is highly sensitive and provides key parameters as disperse surface energy, nanoroughness, polarity, acid/base characteristics, HSP values, isotherms and adsorption energy distribution functions. But, so far there has been no commercial instrument, which fulfilled all practical requirements in terms of concentration ranges, number of probes, flexibility and simply operational efficiency. After 20 years of  practical experience as a dedicated IGC service laboratory, Adscientis launches now NeuronIC, the really smart surface analyzer.
