Micropore physi-/chemisorption analyzers:
autosorb iQ
Micropore physisorption / chemisorption analyzers
upon request
These high-sensitivity gas sorption analyzers use proprietary small cold-zone technology for detailed micropore size distributions of up to three samples simultaneously. They perform the most challenging measurements of zeolites, activated carbons, and MOFs, for novel materials research in environmental and industrial applications such as gas storage and supercapacitors. Their internal vacuum pumps and dedicated sample preparation stations minimize bench space. They are available in different configurations as chemisorption units, still with full physisorption capability, for all-in-one catalyst characterization.
