• Description:
  Standard Reference Material (SRM) series 2951 to 2958 (5 micrograms to 1000 micrograms) Respirable Alpha Quartz on Filter and SRM series 2961 to 2967 (5 micrograms to 1000 mircograms) Respirable Cristobalite on Filter were prepared gravimetrically by depositing SRM 1878 a Respirable Alpha Quartz and SRM 1879 a Respirable Cristobalite on filters, respectively. These new SRMs are developed to assure the quality of respirable crystalline silica measurements using x-ray diffraction and infrared spectrometry around the regulatory limits that are enforced by the Occupational Safety and Health Administration (OSHA). The mass of silica determined by highly sensitive, but non-polymorph-specific, inductively coupled plasma optical emission spectrometry (ICP-OES) was successfully used to calculate the mass of polymorph-specific crystalline silica on filter after all sources of Si on the new SRMs were carefully analyzed. The certified values of alpha quartz in SRMs 2951 to 2958 and cristobalite in SRMs 2961 to 2967, respectively, were established from the gravimetric preparation values and the spectrometric measurement values.
