Analysis of Metals in Aerosols on Air Filters

This application note demonstrates measurement of metals, especially toxic heavy metals, in aerosols on air filters, using the NEX DE EDXRF analyzer. Element analysis of aerosols and particulate matter released in smokestacks and other industrial gas discharge is vital to ensure that environmentally acceptable levels of toxic and hazardous elements are released properly into the air. Monitoring smoke or other gaseous waste is important in many areas, such as industrial manufacturing, coal-fired power plants, chemical and plastics production, etc., in order to minimize air pollution and the release of toxic metals in compliance with US EPA and other world and regional or local governing regulations.
