The Hiden Catlab mass spectrometer/microreactor system is an integrated analytical tool for characterisation of catalyst performance and for analysis of thermal reaction processes at precisely controlled programmable temperatures to 1000°C.
The integrated design concept enables full automated control of up to eight gas streams, of furnace temperature and ramp rate, and of mass spectrometer operation and spectral analysis, all from a single software suite.
High system sensitivity enables operation with powder samples of just 100 milligrams. Sample loading is via a cartridge-style quartz tube which inserts vertically and reproducibly into the reactor vessel, with the sample then directly above the close-coupled evolved species probe mounted internally to the reactor. The sampled gases are then fed for analysis directly to the mass spectrometer, with a total response time of less than 500 milliseconds.
Properties including adsorption isotherms, metal dispersion, surface acidity are readily determined, the mass spectrometer providing continuous, simultaneous multicomponent product measurement.
