Quantachrome autosorbIQ gas sorption analyzer

The Anton Paar™ Quantachrome autosorbIQ automated gas sorption analyzer is used to measure chemisorption (hydrogen, methane, other reactive gases) and physisorption (nitrogen) processes. The physisorption mode allows acquisition of data to determine surface area (via BET analysis of the isotherm), average pore size (via BJH or DFT isotherm models), and pore volume (via BJH or DFT isotherm models) on non-porous, mesoporous, and microporous materials. Featuring an extended range physisorption and chemisorption pressure transducer, system is capable of determining specific surface areas below 0.01 m²/g, active areas, pore volumes, and pore size distributions down to 0.35 nm in solid porous samples. Unit has 4 degas and 3 analysis ports for physisorption measurements on multiple samples simultaneously. Note sample degas and isotherm acquisition can require several hours of instrument time per run. Mesopore samples usually require ~4hrs total; micropore samples generally require longer degas times and so can require up to 18h of analysis time. The mass of sample needed for analysis depends on its surface area; recommended total surface area for a surface area measurement is 2 m² and for a pore size measurement it is 10 m². So for example if your sample has a specific surface area of 200 m²/g, it will require ~50 mg of material for a good analysis. The facility also maintains a legacy (older and slower) Micromeritics™ ASAP 2020 gas adsorption/surface area measurement apparatus.
