AMI-300HP/RHP
High Pressure Chemisorption Analyzer
Product Category: Chemisorption
Industry: Particle and surface science
Supplier: AMI
Description
Based on our successful AMI-300 instrument, the AMI-300HP represents an automated high pressure chemisorption analyzer. The AMI-300HP performs dynamic high pressure temperature-programmed experiments designed to reach 100 bar
(higher pressures available in custom instruments). When integrated with a pump, the AMI-300RHP provides the most sophisticated and automated characterization and micro-reactor instrument in the industry. The sophisticated design allows for the system to also double as a single-station Bench-top reactor.
Functions
The AMI-300HP can be designed with any number of pressure and temperature ranges in mind. The AMI-300HP utilizes our proven technology to perform:
| High pressure isothermal reaction studies | Temperature programmed reduction/oxidation/desorption (TPR/O) |
| Pulse chemisorption | Catalyst treatment |
| Pulse calibration | Dynamic BET (optional) |
Up to 99 procedures can be linked together back-to-back to provide a complete character ization experiment. Routine experiments can be designed and stored for easy retrieval.
The AMI-300RHP is also able to perform:
- Temperature programmed reaction experiments with vaporized liquids (TPRx).
- High pressure chemisorption experiments
Fully Automated, High Pressure Chemisorption Analyzer and Reactor System
Features include:
- A clamshell furnace capable of 1200°C (reactor type limits max temperature) with ramp rates from 1°C to 50°C per minute.
- High-precision mass flow controllers (MFCs) to ensure TCD baseline stability
- A heat-traced stainless steel flow-path to alleviate concerns of condensation and to provide an inert surface.
- A highly linear Thermal Conductivity Detector (TCD)
Options for:
- Dynamic BET
- Quartz Reactor
- Vacuum Activation
- Liquid delivery
- Inconel, Hastelloy, or other high temperature reactors
- Sub-ambient (-130°C or lower) temperatures
Computer Control and Data Acquisition
The AMI-300HP is fully-automated for ease of use and reliability. The control portion of the software controls and regulates all valve positions, temperatures, flow rates, and detector parameters. Data acquisition occurs at a selected rate for optimum performance. The front panel screen shows the status of the unit at a glance. This screen provides information on the position of all valves, type of gas connected to each port, temperatures, and detector signal.
The data handling package allows the user to display and integrate signal peaks, calculate chemisorptive parameters, and overlay data.
Choice of Detectors
With the AMI-300HP you can use the standard thermal conductivity detector or choose other detectors of your choice. We supply integrated mass spectrometers that can be used in addition to the TCD. In addition, we can incorporate any detector that provides an analog output or can communicate through Dynamic Data Exchange (DDE).
