Chemisorption and high pressure adsorption
iSorb HP1
High pressure gas sorption is an important characterization technique in the study of microporous materials for gas separation. The measured adsorption and desorption isotherms are generated fully automated and can vary over a wide range of pressures (0,0005 up to 200 bar) and temperatures (0°C to 400°C).
The iSorb-HP1 uses two high pressure transducers for improved accuracy over the entire pressure range. Samples can be prepared by degassing in-situ in the stainless steel sample holder.
AutoSorb iQ
Especially catalysts surfaces are reactive to form chemical bonds with certain gases, known as active sites. H2, CO2, O2, NH3 are mainly uses gases to detect the total number of these active sites.
The AutoSorb iQ is a state-of-the-art manometric/volumetric gas sorption analyzer is designed for all kind of fully automatic flow-based chemisorptions experiments, which include temperature programmed reduction, oxidation and desorption (TPR, TPO, TPD) and optionally pulse titration for quantitative analysis (with automatic loop injection). Everything is detected by a powerful build-in TCD detector.
A vapor generator is build-in the manifold chamber, heated and thermostatically controlled. Beside all kind of possible vapors (pyridine, ammonia, toluene,…), this option also offers the possibility for the recording of H2O-isotherms.
