  • This Reference Material (RM) 8786 is the filter blank for RM 8785 Air Particulate Matter on Filter Media.

  • 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.

  • RM 8785 consists of only the fine fraction (nominally < 2.5 µm aerodynamic diameter) of SRM 1649a Urban Dust re-suspended in air and filtered onto quartz-fiber filter.

  • RM 8785 was produced at SRI International by re-suspending SRM 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 RM 8786 consists of a single production blank filter with a 37 mm diameter.

  • Although RM 8785 value assignments for total carbon, elemental carbon and organic carbon are not corrected for blank carbon, intercomparison of laboratories and methods involving chemical speciation may warrant blank correction and will find the availability of RM 8786 useful.

  • Manufacturer: NIST ( National Institute of Standards and Technology)
