Dynamic BET Surface Area Analysis System — Applications and Technical Features
Application Scope
- Designed for BET surface area analysis, particularly suitable for quality control (QC) applications
- Supports single-point or multi-point Dynamic BET testing (Single / Multiple Point Dynamic BET)
- Applicable industries:
- Catalyst research
- Pharmaceuticals
- Battery manufacturing
- Oil and gas
- Building materials
Measurement Principles
- Dynamic BET method: Uses mass flow controllers (MFCs) to precisely control nitrogen partial pressure for flow-based gas adsorption measurements.
- Reduced errors from insufficient desorption: Calculates results using the adsorption peak rather than relying on the desorption process, improving measurement accuracy.
Instrument Features & Benefits
- Fully automated operation with up to four samples analyzed simultaneously
- Built-in dual MFCs (70 mL/min and 30 mL/min) for precise gas flow ratio control and high repeatability
- Software functions:
- Automatic adjustment of nitrogen partial pressure
- Automatic Dewar lift/lower control
- Automatic TCD zeroing
- Equilibrium condition detection
- Automatic data storage and offline analysis
- Automatic correction of adsorption data
- Ideal for high-throughput testing and rapid screening in factory environments
