Application

This Standard Reference Material (SRM) is intended for use in evaluating analytical methods for the determination of selected polycyclic aromatic hydrocarbons (PAHs) and nitro-substituted PAHs (nitro-PAHs) in diesel particulate matter and similar matrices.

Features and Benefits

  • A unit of SRM 1650b consists of a bottle containing approximately 200 mg of diesel particulate material
  • Metrological traceability is to the International System of Units (SI) unit of mass expressed as a derived unit of mass fraction
  • Information on product description, disposal, and transportation is available in the accompanying MSDS
  • The enclosed NIST certificate contains details on the expiry date, warning to users, instructions for right storage and use, preparation, and analysis of the RM

General description

The particulate material used for the preparation of SRM 1650b was collected from the heat exchangers of a dilution tube facility following 200 engine hours of particulate accumulation. Several direct injection four-cycle diesel engines, operating under a variety of conditions were used to generate this particulatematerial. Therefore, while the sample is not intended to be representative of any particular diesel engine operating under any specific conditions, it should be representative of heavy-duty diesel engine particulate emissions. All of the chemical constituents for which certified and non-certified values are provided, are naturally present in the diesel particulate material. The certified values for the PAHs are based on the agreement of results obtained at NIST from two or more independent analytical methods. SRM 1650b is valid, with the measurement uncertainty specified, provided the SRM is handled and stored in accordance with instructions given under “Instructions forUse” in the certificate.

Epidemiological studies have shown that exposure to particulate matter (PM) is associated with adverse health effects. Inhalation of fine particulate matter (PM2.5) is associated with elevated pulmonary diseases. However, the molecular mechanism underlying the initiation of lung inflammation following inhalation
