Physisorption Analyzer Autosorb 1
The Autosorb-1-C, one of the Autosorb-1 Series, is capable of these functions:

Surface area analysis
Mesopore size distribution
Standard micropore methods
Advanced low pressure micropore analysis
Kinetic studies
Chemisorption methods
Five (5) pressure transducers
Very low surface area analysis with krypton
Sample preparation by high vacuum
Built-in 5-gas chemisorption system
Sample preparation/activation by gas flow

The Autosorb-1-C offers total precise, chemisorption/ physisorption measurements.
Unattended chemisorption measurement with automatic transfer from sample preparation to analysis and with small bench-space requirements. Automatic repeat measurement of isotherm following evacuation provides complete weak and strong chemisorption data without operator intervention.
Sample preparation with flow, vacuum or static conditions under programmable heating rates at temperatures up to 1,100°C. PC programmable temperature controller with auto-tuning functions offers limitless number of preparation routines with guaranteed temperature accuracy.
Applications include characterization of metal dispersion of reforming catalysts, acid site distribution of polymerization catalysts, crystallite size of hydrogenation catalysts, heats of adsorption and much more.
Compatible with broad range of gases and vapors including hydrogen, carbon monoxide, ammonia and cyclohexane.
