Rupprecht & Patashnick is pleased to announce the future availability
of a black carbon sensor for use with the firm's TEOM
monitor. The Aethalometer Module can be added to thousands of
TEOM monitors currently deployed worldwide. The new unit provides
a continuous output of the black carbon contained in particulate
matter. It is the outgrowth of a cooperative venture between R&P
and Magee Scientific, the developer of the Aethalometer monitor.
A prototype unit is shown at right.
The Aethalometer Module is a simple and cost-effective means for
existing and new owners of TEOM monitors to add carbon measurement
to their monitoring setup.
The measurement of black carbon (BC) in ambient particulate matter
(PM) has gained importance as air monitoring agencies and scientists
seek to learn more about the health effects of airborne particles.
Black carbon is often a good indicator of the elemental carbon found
in ambient PM, and can also be used to gauge the manmade influence
upon the environment. Small soot particles are often the result
of combustion processes from sources such as diesel engines or power
plants. They can also be generated by forest fires.
The Aethalometer measurement approach has become a well-accepted
method in scientific circles for assessing the elemental carbon
content of airborne particles. It has recently received interest
among ambient air monitoring agencies as well.
By offering the Aethalometer Module, R&P is providing a convenient
means of adding black carbon measurements to the continuous particle
mass information generated by the TEOM monitor. Results generated
by the Aethalometer Module are stored by the TEOM monitor along
with the other information generated by the monitor. The new Aethalometer
unit does not require any programming or setup, and is very easily
connected to the bypass flow of the TEOM monitor (see diagram below).
The output signal from the black carbon device is transmitted through
a cable to the control unit of the TEOM monitor, where the black
carbon values are displayed and stored.
R&P anticipates that the Aethalometer Module will be available
for commercial delivery at the beginning of the second quarter of
2004. Click here for
