Rigaku NEX CG EDXRF: Analysis of Heavy Metals in Aerosols on Air Filters

Share Article

Applied Rigaku Technologies, Inc. announced a fast and simple method for the measurement of heavy metals in aerosols on air filters. Monitoring such emissions is essential in industrial manufacturing, coal-fired power plants, chemical and plastics production and other areas and the new method demonstrates the effectiveness of the Rigaku NEX CG energy dispersive X-ray fluorescence (EDXRF) spectrometer for the analysis of atmospheric particulates.

Applied Rigaku Technologies, Inc. today announced a fast and simple method for the measurement of heavy metals in aerosols on air filters. The new method is detailed in Application Note #1061 and demonstrates the effectiveness of the Rigaku NEX CG energy dispersive X-ray fluorescence (EDXRF) spectrometer for the analysis of atmospheric particulates. Monitoring such emissions is essential in industrial manufacturing, coal-fired power plants, chemical and plastics production and other areas in order to quantify air pollution and maintain compliance with US EPA and other world and regional governing regulations concerning the airborne release of toxic metals.

Element analysis of aerosols and particulate matter released by smokestacks, and other industrial gas discharge, is critical to ensure that toxic and hazardous elements are not released into the air improperly nor exceed environmentally acceptable levels. The Rigaku the NEX CG EDXRF analyzer, with polarized and secondary target excitation, is shown to be a powerful tool to help ensure compliance while enabling both analysts and technicians to easily conduct the required analytical protocols.

The method shown utilizes a combination of secondary target excitation, with a high resolution silicon drift detector (SDD), to deliver optimal EDXRF sensitivity and selectivity for the measurement of metals in aerosols on air filters, including chromium (Cr), gallium (Ga), arsenic (As), selenium (Se), silver (Ag), cadmium (Cd), barium (Ba) and lead (Pb). The NEX CG analyzer is capable of analysis of elements from Na – U, making the XRF technique ideal for other elements on air filters, as well.
