Descrizione generale

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.

Applicazioni

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.

Caratteristiche e vantaggi

  • 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

Australian Aboriginal populations have unacceptably high rates of bronchiectasis. This disease burden is associated with high rates of detection of pathogenic bacteria, particularly non-typeable Haemophilus influenzae (NTHi). While there is evidence to suggest that exposure to inorganic particulate matter (PM)
