R&P
Wins USEPA Contract
for On-Vehicle Diesel Particulate Mass Measurement
Albany, New York, April 7, 2003 - Rupprecht & Patashnick Co.,
Inc. (R&P), has been awarded a research and development contract
by the U.S. Environmental Protection Agency (USEPA) in Ann Arbor,
MI, for the design and construction of an On-Board Diesel Particulate
Mass Measurement Module (OBDPM).
The OBDPM will be based upon a miniature version of R&P's TEOM
technology to provide real-time, filter-based, NIST-traceable mass
measurements of diesel particulate matter (PM) while a vehicle is
operating under normal daily conditions. The company had previously
miniaturized the TEOM sensor under contract by the Mine Safety and
Health Administration (MSHA) and the National Institute for Occupational
Safety and Health (NIOSH), to provide a battery operated wearable
personal continuous dust monitor (PCDM) for the mining community.
This USEPA contract extends the application and integration of a
continuous PM mass sensor into an on-vehicle system.
The objective of this contract is to provide USEPA with two OBDPM
units for the agency's development of portable emission measurement
systems. These systems will be used for on-board collection of real-world
exhaust emissions data from on-highway and non-road vehicles. The
work will be performed over an eighteen-month period, with the first
phase to be completed later in 2003.
R&P's current instrumentation for diesel particulate matter
measurements includes the TEOM
Series 1105 Diesel Particulate Monitor and the Model
6186 FRM Exhaust Filter Holder System.
R&P specializes in the development and manufacture of innovative
instrumentation for the measurement of PM mass and its chemical
components. For more information concerning R&P go to www.rpco.com
