Quantachrome Instruments Surface Area and Pore Size Analyzer Autosorb® IQ - MP

The gold-standard in micropore analyzers. Patented, dry high-vacuum system, ultra-stable transducers, three pressure ranges seamlessly overlap, and up to three micropore stations. Turbo-level degassing and metal O-rings and gaskets in critical measurement zones perfectly complement low starting pressures for true micropore analysis. This is also the model for very low surface area and thin film analyses using krypton gas. 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.
