Catalyst Characterization in an Extended-Pressure Environment AutoChem 2950 HP Chemisorption Analyzer Superior Performance Under Extended Pressure Micromeritics’ AutoChem 2950 HP Chemisorption Analyzer is an automated high-pressure catalyst characterization system that is capable of preparing and analyzing samples at elevated pressures up to 1000 psia and at temperatures from -100 to 1100 °C. The instrument can perform a variety of experiments including pulse chemisorption, BET surface area, temperature-programmed reduction (TPR), desorption (TPD), oxidation (TPO), and reaction analyses....

Typical AutoChem 2950 HP Applications Catalysts The active surface area and porous structure of catalysts have a great influence on production rates. Limiting the pore size allows only molecules of desired sizes to enter and leave; creating a selective catalyst that will produce primarily the desired product. Chemisorption experiments are valuable for the selection of catalysts for a particular purpose, qualification of catalyst vendors, and the testing of catalyst performance over time to establish when the catalyst should be reactivated or replaced. Fuel Cells Platinum-based catalysts...

Hardware Versatility AutoChem 2950 HP Hardware Advantages Cold Trap to remove condensable species – the Cold Trap is easily bypassed to improve response time The AutoChem HP features stainlesssteel construction, fully automated flow control and pressure control, an embedded microprocessor with real-time control, and an intuitive graphical user interface for reactor control. Like the AutoChem 2920, the AutoChem 2950 HP features a temperature-controlled, stainless-steel flow path to provide a stable inert operating environment and reduce the potential for condensation in the flow path. The...

• The extremely low volume of the internal plumbing minimizes peak spreading and signicantly enhances peak resolution. Furthermore, it reduces the time lag between sample reactions and the corresponding detector response. • A cold trap can remove certain substances before the gas ow reaches the detector. The cold trap can also be used as a delay path for BET surface area experiments. • Injection loops are provided for injecting carefully measured doses of gases for analyses such as pulse chemisorption. The AutoChem HP is shipped with a 1.0-cm3 loop installed; 0.5- and 5.0-cm3 loops are also...

Software and Reporting Versatility AutoChem 2950 HP Software Features The AutoChem 2950 HP is controlled by powerful Windows®-based software. It provides all the convenient features you are accustomed to when using Windowsbased programs. Point-and-click operations, pull-down menus, access to multiple printers and network drives, multitasking capability, and much more are featured in the AutoChem 2950 HP user interface. In addition, the familiar Windows format reduces the time required for training new operators, resulting in fast start-up and increased productivity. Additional Capabilities...

• Numerous plots can be overlaid for easy comparison of different samples or for comparison of different data reduction techniques applied to the same sample. The operator can also plot two externally derived signals against time or sample temperature (e.g., mass spectrometer and • Integration of mass spectrometer data flies, which allows the manipulation of the TCD and mass spectrometer simultaneously.
