Application

Titanium dioxide is primarily intended for calibrating and testing gas sorption instruments used to determine the specific surface area of porous solids and powders.

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.
