Optical Open-Path Monitors
Beginning this month, the AMS pilot will be verifying commercially
available optical open-path monitors from four companies. The test
will be conducted at field locations selected to accommodate
participating companies and will continue into March.
Companies whose monitors are scheduled for testing during January,
February, and March are:

Optical open-path monitors are used at facilities concerned about the
concentrations of volatile organic or inorganic pollutants emitted into
the air. These instruments continuously monitor target compounds
over path lengths from tens to thousands of meters and provide early
warning of potential noncompliance conditions or emergency release
situations. In contrast, "grab sample" analysis by standard methods
takes more time, addresses only a single point in space, and is non-
continuous.
The monitors to be tested rely on a light source (ultraviolet, visible, or
infrared) and a detector that, used together, identify and quantify the
levels of targeted chemicals in the atmosphere. Testing involves
challenging these monitors with gas samples under realistic operating
conditions.
See next page for additional information.
The AMS pilot is one of 12 pilots in the U.S. Environmental Protection Agency's Environmental
Technology Verification Program. ETV was established to accelerate the development and com-
mercialization of improved environmental technologies through third-party verification testing and
reporting of the technologies' performance. The ETV process provides purchasers and permitters
with an independent assessment of the technology they are buying or permitting and facilitates multi-
state acceptance. For further information, contact Helen Latham at Battelle, 505 King Ave., Columbus,
Ohio 43201-2693; Phone 614-424-4062; Fax 614-424-5601; E-maillathamh@battelle.org.

Vendors Invited
To Join Test
The AMS pilot is considering conducting a
verification test for portable, on-board devices
that monitor emissions from vehicle tailpipes
while the vehicle is on the road. These
instruments can be placed in the vehicle to
perform the test, in contrast to the current
practice of operating the vehicle on a
stationary dynamometer,
On-board emission monitors offer the
potential for more realistic emission
measurements than can be obtained from
dynamometer testing in a laboratory.
Interested vendors should contact Tom Kelly
at Battelle (phone 614-424-3495 or e-mail
kellyt@battelle.org).

Optical Open-Path Monitor Performance
Characteristics to be Verified
Performance characteristics to be verified during the test of
optical open-path monitors include:
* Detection limit
* Concentration linearity
* Accuracy
* Precision
* Interference effects.
The test procedures will involve providing a range of known
concentrations of various target compounds to each monitor.
Measurements will be made with different path lengths (the
distance the light travels from the monitor's light source to its
detector), integration times, source intensities, and numbers
of replicated measurements to assess the verification factors
listed above.
Testing will take three days and will require each participating
vendor's technology to detect three different compounds.
For example, for the Fourier Transform Infrared (FTIR)
monitors, testing for tetrachloroethylene will take place on
day one, cyclohexane on day two, and ethylene on day three.
The test/QA plan, which provides details of the testing
procedures for the optical open-path monitors, is available on
the ETV web site at
http://www.epa.gov/etv/test_plan.htm#07.
