詳細

詳細

The SRM material was prepared from single crystal nodules of Brazilian quartz that, upon comminution were reduced to a respirable powder with a median particle size of 3.3 µm.

Each unit of SRM 1878b contains approximately 5 g of powder bottled in an argon atmosphere.

アプリケーション

Respirable alpha-quartz standard reference material (SRM) is intended for the preparation of calibration standards used in quantitative analyses of α-quartz via X-ray powder diffraction.

特徴および利点

• Available with a certificate documenting NIST-certified value of crystalline phase purity and lattice parameter. The information values include particle size distribution, as determined by laser scattering. 
• Certified values are metrologically traceable to the International System of Units (SI) and SI-derived units of mass fraction.
• The NIST certificate is provided with storage and use instructions
