This Standard Reference Material (SRM®) is an air particulate sample reduced in particle size to simulate PM2.5 air particulate matter (particles with an aerodynamic equivalent diameter of 2.5 µm) and deposited on a polycarbonate filter membrane. It is primarily intended for use in the evaluation and calibration of methods of analysis for common and toxic elements contained in various fractions of airborne particulate matter collected on filter media. A unit of NIST-2783 includes two loaded filters and two blank filters. /// Sample value(s) - please ask for current certificate.
