Characterization of solids, e.g. Zeolites , by Inverse Gas Chromatography (IGC) delivers
precise and  unique values about surface energy, size exclusion and acid/base properties.
Proven software, as our own development, experience and proven operation conditions
are requirements, while the use of standard GCs allows great flexibility plus 2 channels.
The BEA t ype zeolite has h igher surface energy γsd than Silicalite-1, 237 vs. 192 mJ/m2, whereas Silicalite-1 shows a very strong size exclusion effect. BEA is more polar and has stronger electron donor (acid) andacceptor (base) properties.
