Physisorption and chemisorption measurements
The analytical requirements of the modern investigation laboratories have become, in recent years, more and more sophisticated. Nowadays the researchers are trying to discover and understand the morphology of complex porous structures using different techniques. Gas adsorption analysis remains one of the most useful and reliable.
Microporous and ultramicroporous materials (as zeolites and activated carbons) show a really complex porous structure. The determination of the pore size and pore volume in these solids is complicated by the extremely small pore diameter, which is in the range of gaseous molecule dimension as nitrogen or argon. The physical interpretation of the adsorption isotherms obtained on these materials is almost impossible unless the experimental data are collected in a very sophisticated way. Only extremely reliable experimental permit to apply the most recent calculation models.
On the other hand, some standard physisorption measurements have become a real routine in quality control labs of factories producing powders or porous materials. Parameters as specific surface area or pore size distribution automatically define the quality and/or the application of most porous products.
In QC analysis, the most important features required by an analytical instrument are ease of use and automation, as very often several operators should operate the same hardware. Of course, the results must show the same reliability and reproducibility regardless the specific user’s knowledge.
