Magee microAeth Model AE51 is the world's first ever real-time, pocket-sized Black Carbon aerosol monitor. The instrument can be placed virtually anywhere and provide real-time information about the concentration of black carbon in the atmosphere.

The instrument can operate continuously for up to 24 hours on a single battery charge. An external back up battery option is available for longer run times. The air sample is collected and analyzed within the microAeth instrument on T60 (Teflon coated glass fiber) filter media. The filter media is constructed within a filter ticket form for easy handling and secure placement into the instrument. The filter tickets can be uniquely marked for archiving purposes and / or subsequent analysis.

Application: Environmental Monitoring, personnel pollution monitor

The AE42 Portable Aethalometer measures optical absorption by suspended aerosol particles at two wavelengths: 880 nm (IR), quantitative for the mass of ‘Black’ Carbon; and 370 nm (UV), indicating aromatic organic compounds. The instrument’s analytical performance is identical to the “full size” AE22, but it is constructed in a small portable case with an internal battery providing several hours of mobile operation. The AE42 can also be operated from an AC transformer or by cables from an external battery or automobile power outlet. This instrument is widely used for studying indoor air quality, and for the mobile mapping of the air quality impacts of localized sources.

The Portable Aethalometer may also be supplied with “seven wavelength Spectrum” optics upon request. The AE42’s can be supplied with a GPS position receiver kit that attaches to the instrument's COM port.

The 'rack mount' model is constructed in a standard 19-inch enclosed chassis. The instrument simultaneously samples and measures the mass concentration of black carbon particles in the air. A digital display/keypad combination interface is used to operate, monitor, calibrate, and service the instrument. The measurement data are stored within the instrument on removable media.

The AE22 Aethalometer measures the optical absorption of carbon particles at two wavelengths: 880 nm (IR), quantitative for the mass of ‘Black’ or Elemental Carbon; and 370 nm (UV), indicating the presence of aromatic organic compounds such as are found in wood smoke, biomass-burning smoke, and tobacco smoke.

The AE31 Aethalometer measures optical absorption by suspended aerosol particles at seven wavelengths, from 370 nm (UV) to 950 nm (IR). Interpretation of the differences in optical response across the wavelength spectrum reveal information regarding aerosol size distribution, physical properties, and assist in identifying the primary components.

The Magee Scientific SootScan™ Model OT21 Optical Transmissometer bench top analyzer has been developed as a simple and robust way of assessing Black Carbon particulate matter (PM) from a variety of sample filters. The analysis can be easily performed in the field or the laboratory, and requires less than thirty seconds to provide optical attenuation and BC mass concentration results.
