A number of recent studies have shown how mass spectroscopy can further increase the functionality of the Autochem range of catalyst characterization Systems. The integration of the MKS Cirrus 2 Atmospheric Pressure Gas Monitoring System, based around a quadropole mass spectrometer, to the Autochem instruments, provides an effective way of extending their versatility, while maintaining ease-of-use and a space-saving footprint.
The Micromeritics AutoChem Catalyst Characterization Systems already have a proven history as powerful instruments for laboratory catalyst research. Both the Autochem II 2920 and the Autochem 2950 HP are fully automated mini-laboratories in one compact, yet sophisticated, package.
The Autochem II 2920 chemisorption analyser can carry out a number of analytical techniques including temperature-programmed reduction, pulse chemisorption (dynamic adsorption), desportion and oxidation and reaction analysis, helping to determine catalysis properties such as the active metal surface, percentage of metal dispersion and surface acidity and acid strength. When used with the cryocooler attachment analysis over a considerable temperature range (-100 °C to 1100 °C) can be achieved.
The Autochem 2950 HP is a high-pressure (up to up to 1000 psia) catalyst characterization system that functions as a microreactor, additionally providing an affordable alternative to costly pilot plants for small businesses. The addition of the MKS Cirrus 2 produces a further raft of analytical (quadropole mass spectrometry) functions allowing on-line monitoring of gases e.g. hydrocarbons, solvent vapours, freons and corrosives, relevant to the Autochem's performance and function.
Because the whole operation is controlled by Micrometrics/Cirrus interface software that runs inside the Cirrus Process EyeTM Professional software, accessed by its own menu, compatibility issues are not a problem. The advanced analytical power of Quadrupole Mass Spectrometry almost effortlessly made available; the whole set up is designed to enable the user to collect maximum information, automatically, and as simply and reliably as possible.
