For the characterization of catalytic materials is the knowledge of the specific surface area and pore size distribution is as important as the investigation of the catalytic properties themselves
The BELSORP-max is a static-volumetric Sorption measuring instruments for the measurement of physisorption of gases and vapors. The BELSORP-max comes standard with three measuring port, where port is equipped as High precisions port 3 (Port 3: 3 pressure sensors, 133 kPa, 1.33 kPa and 0.0133 kPa). If desired, also issued a port be equipped as High precisions port. The Edelstahlmanifold with pneumatic valves enables besides the use of common gases and vapors even in the use of different media, or hydrogen. For the measurement of sorption processes in the low temperature (eg O 2),a cryostat (He-cooling, limiting the measuring time) are not integrated.
The TPDpro extension (optional) in addition to catalyst materials are characterized by Chemi-sorption process in the flow. Smallest changes in concentration in the MFC-regulated flow of gas through highly sensitive thermal conductivity detectors eva luiert. The control and analysis software includes all test and evaluation procedures that are essential for a comprehensive characterization (pulse adsorption, dispersion metal-on, TPD, TPO, TPR / TPRX).
