Make and Model:
• Make: Anton Paar
• Model: ChemBET Pulsar
• Date of Installation: March 2023
Description:
The ChemBET Pulsar is a fully automated chemisorption analyzer designed for high-precision titration and surface characterization. The system is equipped with TPRWin software, allowing for programmed analysis sequences, including metal area and dispersion determination. An automatic loop injector and gas switching enhance accuracy and efficiency. The Pulsar uses a highly sensitive Thermal Conductivity Detector (TCD), resistant to oxidation and ammonia, ensuring baseline stability and reproducible signals. The system is optimized for a wide range of gases, with high-temperature quartz sample cells and in-cell thermocouples for accurate sample temperature measurement.
Features:
• Automatic Gas Switching:
Switch between 4 gas ports seamlessly for enhanced control during analysis.
• Forced Air Cooling:
The furnace features automatic forced air cooling to accelerate throughput and enable quicker sample preparation.
• Variable Gas Flow Rate Control:
Precisely adjust gas flow rates for customized analysis.
• Sample Cell Bypass:
Allows flexibility in analysis, bypassing the sample cell when required.
• In-Line Cold Trap:
Equipped with a bypass for efficient trapping of condensable gases.
• High-Temperature Heating:
Includes a heating mantle capable of reaching 350°C and a high-temperature furnace with a maximum capacity of 1100°C.
• Advanced Analysis Techniques:
o Pulse Titration: Metal area measurement.
o Temperature Programmed Reduction (TPR).
o Temperature Programmed Desorption (TPD).
o Temperature Programmed Oxidation (TPO).
o Temperature Programmed Surface Reaction (TPSR).
