Cryosync: Cryocooler Accessory


AUTOSORB SURFACE AREA & PORE SIZE BY MICROPORE GAS SORPTION


The gold-standard in micropore analyzers. Patented, dry high-vacuum system, ultra-stable transducers, three pressure ranges seamlessly overlap. Also available with optional 0.1 torr transducers (XR models)
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 six statistical mechanics-based models describing different pore shapes, chemical nature of the surface, specific adsorbate and temperature pairs, and unique ability to fundamentally account for surface roughness and heterogeneity of real solid surfaces.

XR models: 0.1 torr transducer extends pressure range down to 10-8 P/Po (N2, 77K)

Reproducibility in the ultra-low pressure range is demonstrated in the XR model using 0.1 torr
transducer.

iQ-AG

iQ-Chemi

The AnyGas model uses any suitable gas for high resolution, high sensitivity physisorption studies by means of a 1000 torr transducer and a rotary pump. It is optionally offered with up to three analysis stations, and is up-gradeable to Chemi and MP versions.

The Chemisorption model has the necessary additional features for characterizing catalysts using flow methods of preparation and static isotherm measurements, yet retains all of the advanced physisorption abilities of the MP version. A second and even a third physisorption station can be added.
