Materials and methods
- Principles of method if other than guideline:
- This test method allow the determination of the specific surface area of substances in powder or in granulate form according to the Brunauer, Emmet and Teller (BET) principle.
- GLP compliance:
- no
- Type of method:
- BET
- Details on methods and data evaluation:
- 4.1 Preparing the Instruments
Rinsing: valves 1, 2, 3, and 4 are open (pin has been removed), the blocking valve 5 is locked. Both the adsorption vessels are still on the AREA-Meter. The nitrogen stream is on (20%).
5. Evaluation
The nomographic evaluation is the most simplified way of calculating specific surface areas.
The specific surface area is calculated using four different parameters.
