Nanotechnologies. Method to quantify air concentrations of carbon black and amorphous silica in the nanoparticle size range in a mixed dust manufacturing environment Ingestion-build-52208 This document specifies the essentialWhat is this standard about? This document provides guidelines to quantify and identify air concentration (number of particles cm3) of particles of carbon black and or amorphous silica by size in air samples collected in a mixed dust industrial manufacturing environment. The method is defined for air samples collected with an electrical low pressure cascade impactor (ELPCI). on a 25 mm polycarbonate substrate. The method is suitable for sampling in
