Europa Environmental are the exclusive distributor of the Magee Scientific Aethalometer^®, the most-widely-used instrument for the real-time measurement of ?Black Carbon' aerosol particles in the atmosphere. These particles reduce visibility; adversely impact human health; and contribute to local and global climate change. Aethalometers are installed on all continents: from cities in China to the South Pole, from the Sahara Desert to the Amazon jungle.

Available in two (AE22) or seven (AE31) channel versions providing additonal information about the "nature" of the carbon being measured in near real time. The Aethalometer was recently declared the instrument of choice of the UK Air Quality Network when DEFRA bought 22 units to deploy accross the UK to replace the previous and aging Black Smoke monitors.

In addition to Aethalometer models, Magee Scientific & Europa Environmental support scientific research in remote regions, specifically Antarctica. Solar-powered enclosures with satellite radio communications have been used for autonomous webcams; underwater cameras, extremely low-temperature-rated equipment and winter-survivable instrumentation have been developed and used on ?The Ice' for more than a decade.

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 instrument can then record the GPS position input data for mapping in mobile or survey use.

The 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 MicroAeth incorporates the same aethalometer measurement technology which has been used worldwide for over 25 years.

The instrument can operate continuously for up to 24 hours on a single battery charge. The air sample is collected and analyzed within the MicroAeth instrument on a quartz fiber filter strip. Optional filter strips are available which contain unique serial numbers. The serial number can be used to track the filter strip following its use in the MicroAeth for archiving and possible further chemical analysis in a laboratory. All data, including instrument status and BC measurements, are stored using on-board Flash memory. The MicroAeth connects to a PC using a supplied USB cable and interfaces with the intuitive MicroAethCOM PC-based software program. The software is used to program the MicroAeth, view current instrument conditions, and download the collected data. The software also provides Quickview graphs to evaluate data and diagnostic information immediately.

Soon to come, the high altitude version of the MicroAeth specifically designed to measure aerosol black carbon in atmospheric vertical profiling studies. This specially configured instrument will use a high flow rate pump, on-board barometric pressure sensor, and other provisions to properly operate under reduced pressure and temperature conditions. It will also include a Global Positioning System (GPS) for resolving latitude, longitude, and altitude of the instrument while in flight.

The Optical Transmissometer analyzes filter-collected samples for Aerosol Black Carbon ('BC' or 'EC') using 880 nm light, and Aromatic Carbon (‘OC’) using 370 nm light, to match the optical analysis of the standard Aethalometer^®.

Accepts 47, 37 and 25mm diameter filters. Barcode scanner option is available for sample identification. The instrument can be connected to personal computer using included Data Logger software. Constructed in lightweight, bench top case with operation from 12 V DC: line power supply for operation from 110-220 V AC.

The transmissometer analysis is non-destructive, allowing for further chemical analysis to be performed. The instrument analysis process is fully automated and requires no support gases or consumables. A second filter position inside the analysis chamber allows for simlulateous reference (blank) measurement to be made along with the sample measurement.

Analysis results are displayed on the front main screen and communcated externally via COM port to a computer. The data is output in a .csv compatible format for easy importing into spreadsheet application.

The AE45 Aethalometer Module measures optical absorption by suspended aerosol particles at one wavelength: 880 nm (IR), quantitative for the mass of ‘Black’ Carbon.  The aethalometer module has a very small footprint and power consumption requirements, providing a simple and economical means of integrating real-time Black Carbon mass concentration data into any monitoring application.

The modules only consumable item is the filter tape sample roll. Sample flow rate can be monitored using the rotometer mounted on the front panel. Black carbon mass concentration data are streamed out in the form of a 0-5V analog signal from the rear instrument connector. The module can be added to existing PM mass monitors or used standalone with a small pump.
