Autosorb IQ MP Physisorption Analyser (Quantachrome)


We can run CO2, Argon or N2 gas sorption experiments as required.


The Autosorb-iQ is an ideal pore analyser for micropore materials. It enables analyses of extremely low surface area samples and porous thin films using krypton gas at low pressure.

A typical physisorption analysis starts with degassing of the sample. The desired protocol of heating rates, hold times and automatic testing are loaded, and then the iQ takes over. After completing the timed protocol, or sooner if the residual pressure rise passes the user defined test limit, the iQ shuts down the degasser, backfilling the sample cell or leaving it under vacuum if preferred.

Comprehensive physisorption calculations include specific surface area (single and multi-point B.E.T., Langmuir, STSA, t-plot, alpha-s, DR), pore size (BJH, DH, DA, MP, HK, SF, Monte-Carlo, NLDFT, QSDFT) with their corresponding surface area values, Kr-pore size for thin films, heats of adsorption, plus NK and FHH fractals. The DFT library is the most extensive available commercially; no less than twenty three mathematical models describing different pore shapes, chemical nature of the surface and specific adsorbate and temperature pairs.


Highly detailed, precise and accurate measurements to characterize the structure and improve the properties and performance of microporous materials such as zeolites, activated carbons, novel carbon structures (nanotubes, bulk graphenes), MOFs, carbon- and silica-based materials with hierarchical micro-mesopore structure (e.g., CMKs), molecular sieves, new materials for gas storage, improved fuel cells and batteries, membranes, nanofilters, etc., with Kr capability being ideally suited for APIs, thin films, nanosized ceramic and metal powders, and the like.
