SRM 1900_SDS
Application
Silicon nitride powder - specific surface area standard reference material (SRM) is intended to calibrate instruments used to measure the specific surface area of materials, falling within a range of 0.1_m2/g to 1000_m2/g.
Features and Benefits
- SRM 1900 is available with certified specific surface area.
- Certified value is measured using a static volumetric type Brunauer–Emmett–Teller (BET) (nitrogen gas) instrument using a pellet cell.
- The NIST certificate is provided with storage, handling, and use instructions
