Analysis of heavy metals in aerosols on air filters

Measurement of heavy metals in aerosols on air filters is demonstrated. Simple linear empirical calibration is discussed, and performance is shown, for measurement precision and typical detection limits.



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. As a tool to help ensure compliance and proper release, Rigaku offers the NEX CG EDXRF analyzer with polarized and secondary target excitation, giving the analysts and technician alike a fast, simple, yet powerful means of elemental analysis of air filters.

NEX CGRigaku NEX CG delivers rapid qualitative and quantitative determination of major and minor atomic elements in a wide variety of sample types — with minimal standards. Unlike conventional EDXRF analyzers, the NEX CG was engineered with a unique close-coupled Cartesian Geometry (CG) optical kernel that dramatically increases signal-to-noise.
