Workplace atmospheres - Characterization of ultrafine aerosols/nanoaerosols - Determination of the size distribution and number concentration using differential electrical mobility analysing systems (ISO 28439:2011)

This document specifies the determination of the size distribution and number concentration of ultrafine aerosols and nanoaerosols using mobility particle sizers (also called differential mobility analysers). It provides a sampling guideline for occupational hygienists and researchers to effectively characterise and monitor ultrafine aerosol and nanoaerosol exposures in the workplace.
