Surface Area Analyzers rapidly and reliably produces accurate and repeatable surface area and porosity results.It offers a simple, fast, and reliable technique for external surface area measurement - a measurement not readily achieved by static nitrogen adsorption (BET) methods. The surface area analyzer's innovative use of flow permeametry combined with its sophisticated self-adjusting viscous-flow controller enables testing of a wide range of powders and other samples, including materials with surface areas of only several square meters per gram.
Principles of Operation
The surface area analyzer operates on the principle of flow permeametry. By measuring the flow of nitrogen (or any noncorrosive gas) through a sample at various differential pressures, one is able to deduct, through a series of equations, the external surface area of the sample.
Features
- Uses nitrogen or other noncorrosive gases; no expensive gas mixtures required
- Windows-based software handles all control, measurement, data collection, and report generation; manual control also possible
- Compatible with Windows 95 or higher
- Real-time graphical test display depicts testing status and results throughout operation
- Nondestructive testing
- Length of test approximately 5 minutes
- Wide range of acceptable sample types and sizes
- Minimal maintenance required
