Partnership To Develop Ultra-low Propane SRM"
16, 2004, Plumsteadville, PA
Scott Specialty Gases recently announced it has begun preliminary
work to develop a 0.1 parts-per-million (ppm) propane Standard
Reference Material (SRM) precursor for the National Institute
of Standards and Technology (NIST). The project was initiated
at the request of the American Industry/Government Emissions
Research Consortium (AIGER) and will ultimately result in
NIST selling the new propane SRM to emissions testers for
measuring trace amounts of propane in automobile exhaust.
Traceability to a NIST standard is a critical requirement
for calibration gases when complying with EPA environmental
Scott Specialty Gases is the sole-source producer of gaseous
SRM candidates for NIST. In 2002, Scott developed two low
nitric oxide (NO) SRM precursors at 0.5 and 1.0 ppm concentrations,
also at the request of AIGER to facilitate measurement of
low levels of NO in automotive emissions. The NIST/Scott initiative
has resulted in several reactive gas innovations, including
a unique cylinder inerting process that protects calibration
gas against contamination from the cylinder in which the gas
is contained. The process advancement also extends shelf life
of the gas, thereby eliminating the need for annual recertification.
Originally founded in October of 1992, AIGER established a
Cooperative Research and Development Agreement (CRADA) to
develop test instrumentation and techniques for measuring
auto emissions, and to make them readily available commercially.
AIGER s CRADA unites engineers and scientists from the U.S.
Environmental Protection Agency, the California Air Resources
Board and the Environmental Research Consortium (ERC). The
ERC includes representatives from Chrysler, Ford, General
Motors and Navistar and functions under the auspices of the
U.S. Council for Automotive Research (USCAR).
Metrology institutes throughout the world, such as NIST and
the Netherlands Measurement Institute (NMi), often select
Scott Specialty Gases to produce reference standards and cylinder
treatment processes because of Scott s reputation for successful
development of challenging specialty gases. Scott is the world
s largest supplier of EPA protocol gases and is a worldwide
supplier of pure and mixed gases for applications that include
natural gas, environmental, laboratory, industrial, medical
and semiconductor applications. Scott maintains numerous manufacturing
facilities in both the U.S. and Europe. Scottgas.com features
online ordering, eScott; Online Supply Chain Management and
other innovative etools that empower Scott customers to substantially
reduce operating costs.
