Application
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.
Features and Benefits
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
General description
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.
SRM 1878B _SDS
SRM 1878B _CoA
