應用

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.

特點和優勢

• 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

其他說明

Reference/Informational value is provided for the following analytes.
Nitrogen (N), Oxygen (O₂), Water (H₂O), Total hydrocarbon
