High vacuum physisorption/chemisorption analyzers:
autosorb iQ
- High-vacuum physisorption and chemisorption analyzer
- For analysis of BET surface area and active metal area
- For analysis of micropore size distribution
Driven by decades of experience in gas sorption, the autosorb iQ series performs the most challenging measurements of non-porous, mesoporous, and microporous materials with accuracy and precision. Capable of determining specific surface areas below 0.01 m2/g, active areas, pore volumes, and pore size distributions down to 0.35 nm of porous solids in compliance with more than 20 ASTM, DIN, and ISO standard test methods, the autosorb iQ is your gateway to intelligent catalyst characterization.
Key features

Active coolant level control for sensitivity, accuracy, and reproducibility
Rather than relying on passive wicking systems or empirical corrections, the autosorb iQ series combines a 90+ hour analysis Dewar, a coolant-level sensor, and a responsive elevator in an advanced active coolant level control system that ensures highly sensitive and accurate measurements regardless of analysis time.

Analysis flexibility and adaptability
autosorb iQ instruments are customizable to meet your physisorption and chemisorption analysis needs. You can upgrade to two or three analysis stations for increased physisorption throughput. Chemisorption capabilities can be expanded with a built-in thermal conductivity detector (TCD) or integrated mass spectrometer and automated titration loop. Additional options such as a built-in vapor source, extra gas inputs, and more are available to meet your exact measurement needs.

Integrated and highly precise sample preparation
Precisely prepared samples are the foundation of accurate analysis data. Four built-in degassing stations with access to analysis-quality levels of vacuum through a dedicated cold trap ensure that even the most difficult microporous samples are properly prepared for analysis. User-flexible programming of test protocols, including a pressure rise limit and test for completion methods, minimize elutriation and steaming damage to susceptible samples.

Peer-reviewed data reduction methods
The software includes a comprehensive and peer-reviewed DFT method library. These proprietary data reduction methods developed in conjunction with academic partners, like our unique Quenched Solid Density Functional Theory (QSDFT) methods, deliver reliable and accurate pore size distributions.
