Description
This Reference Material (RM) 8786 is the filter blank for the production of RM 8785 Air Particulate Matter (PM)on Filter Media. NIST-RM 8785 is intended primarily for use in the evaluation of analytical methods used to characterize the carbon composition of atmospheric fine-particulate matter (PM) for national air quality monitoring programs. NIST-RM 8785 consists of only the fine fraction (nominally < 2.5 µm aerodynamic diameter) of NIST-1649a Urban Dust re-suspended in air and filtered onto quartz-fiber filter. NIST-RM 8785 was produced at SRI International by re-suspendingSRM 1649a in air and by collecting the aerosol on 320 quartz-fiber filters in each of 7 batches for a total of 2240 filters. A unit of NIST-RM 8786 consists of a single production blank filter with a 37 mm diameter.

NIST provides over 1300 Standard Reference Materials® as well as articles and practice guides describing the development, analysis and use of SRMs.
NIST Standard Reference Materials are used by analytical laboratories in industry, academia and government in order to facilitate commerce and trade and to advance research and development. The SRMs are produced by the engineering laboratory, the material measurement laboratory, and the physical measurement laboratory at NIST. They are available for chemical composition, physical properties, and engineering materials.
