说明

用于制备 SRM 1650b 的颗粒材料是在 200 个发动机小时的颗粒积聚后从稀释管设施的热交换器中收集的。几种在各种条件下运行的直喷四冲程柴油发动机被用于产生这种颗粒材料。因此,虽然该样本不能代表在任何特定条件下运行的任何特定柴油发动机,但它应该代表重型柴油发动机颗粒排放。提供认证和非认证值的所有化学成分天然存在于柴油颗粒材料中。 PAH 的认证值基于 NIST 从两种或多种独立分析方法获得的结果的一致性。 SRM 1650b 有效,并指定了测量不确定度,前提是根据证书中“使用说明”中给出的说明处理和存储 SRM。

本标准参考物质 (SRM) 旨在用于评估分析方法,以确定柴油颗粒物质和类似基质中选定的多环芳烃 (PAH) 和硝基取代的 PAH (硝基-PAH)。

一般描述

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.

应用

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.
 

特点和优势

  • 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
