Features and Benefits

The certified values for multi-point (MP) and single-point(SP) data analysis using the linear form of the single parameter BET equationare presented and evaluated for the Brunauer-Emmet-Teller (BET) specificsurface area, determined through nitrogen gas sorption at liquid nitrogentemperature (77.3 K) using the discontinuous manometric measurement method, inaccordance with ISO 9277:2010.
Reference value is provided for nicotine adeninedinucleotide hydrate equivalent to photocatalytic activity.
Elemental composition, purity,crystalline-phase content, and crystallite size information values are provided for both Anatase and Rutile.
Expiration detailsand instructions for storage, handling, use, and maintenance are provided on the NIST certificate.

Other Notes
