The U.S. Environmental Protection Agency (EPA) has established the Environmental Technology Verification
(ETV) Program to facilitate the deployment of innovative or improved environmental technologies through
performance verification and dissemination of information. The goal of the ETV Program is to further
environmental protection by accelerating the acceptance and use of improved and cost-effective technologies.
ETV seeks to achieve this goal by providing high-quality, peer-reviewed data on technology performance to
those involved in the design, distribution, financing, permitting, purchase, and use of environmental
technologies. Information and ETV documents are available at www.epa.gov/etv.
ETV works in partnership with recognized standards and testing organizations, with stakeholder groups
(consisting of buyers, vendor organizations, and permitters), and with individual technology developers. The
program evaluates the performance of innovative technologies by developing test plans that are responsive to
the needs of stakeholders, conducting field or laboratory tests (as appropriate), collecting and analyzing data,
and preparing peer-reviewed reports. All evaluations are conducted in accordance with rigorous quality
assurance (QA) protocols to ensure that data of known and adequate quality are generated and that the results
are defensible.
The Advanced Monitoring Systems (AMS) Center, one of six technology areas under ETV, is operated by
Battelle in cooperation with EPA's National Exposure Research Laboratory. The AMS Center evaluated the
performance of the bm becker messtechnik gmbh AMESA (Adsorption Method for Sampling Dioxins and
Furans) in monitoring emissions of poly chlorinated dibenzo-p-dioxins (PCDD) and poly chlorinated
dibenzofurans (PCDF). This verification statement provides a summary of the test results.
-------
VERIFICATION TEST DESCRIPTION
The performance of the AMESA was evaluated in terms of relative accuracy (RA), range, data completeness, and
operational factors (ease of use, maintenance, and consumables/waste generated). RA and range were determined
by comparing AMESA results to those from reference samples collected simultaneously using Method 23
sampling trains. Range was determined from measurements over a variety of defined operating conditions that
produced differing levels of PCDD/PCDFs. Data completeness was assessed as the percentage of maximum data
return achieved by the AMESA over the test period. Operational factors were evaluated by means of operator
observations and records of needed maintenance, vendor activities, and expendables used.
A 2.94 thousand British thermal unit per hour, 3-Pass Wetback Scotch Marine Package Boiler (SMPB),
manufactured by Superior Boiler Works, Inc., and located at the EPA Research Triangle Park facility, was used
for the verification test. During this verification test, the SMPB was fully instrumented with continuous emission
monitors for a variety of species including dioxide, carbon monoxide, carbon dioxide, water, and hydrogen
chloride. Reference samples were collected and analyzed for PCDD/PCDFs using Method 23 with several
documented modifications.
QA oversight of verification testing was provided by Battelle and EPA. Battelle QA staff conducted a technical
systems audit, a performance evaluation audit, and a data quality audit of 10% of the test data.
This verification statement, the full report on which it is based, and the test/QA plan for this verification test are
all available atwww.epa.gov/etv/centers/centerl.html.
TECHNOLOGY DESCRIPTION
The following description of the AMESA is based on information provided by the vendor. This technology
description was not verified in this test.
The AMESA long-term sampling apparatus is based on the isokinetic sampling of flue gas and the adsorption of
PCDD, PCDF, and other persistent organic pollutants on an exchangeable adsorption-resin-filled cartridge. The
AMESA system consists of a titanium sampling probe with probe shaft and heat exchanger, a cartridge unit as a
collection point, and a control cabinet. The titanium probe is used for both the isokinetic sampling and cooling of
the hot flue gas to less than 50°C. The cooled flue gas, together with any accumulated condensate, is fed into the
cartridge filled with adsorption resin (XAD-2) via an upstream quartz wool filter. Flue gas conditions are
monitored using sensors in the probe and are used by the control unit to adjust sampling rates to maintain
isokineticity. The PCDD/Fs can be collected over a period of up to one month and then analyzed in a laboratory.
All data required for the subsequent determination of the mass concentration are gathered automatically and
stored on a static random access memory card.

in number of samples collected
• Installation of the AMES A system was completed by a
representative of becker messtechnik within 48 hours
• Effectively operated after 2 hours of training in basic
operation
• Installation of sampling media and removal of sampling
media completed in approximately 15 minutes each(a)
• Approximately 3% down time
No maintenance was required.
XAD-2 and glass wool were used in the sampling cartridges
for sample collection. Methylene chloride, acetone, and
toluene were used to rinse the probe liner and sampling
tube.(a)
Installation and removal of sampling media were not typical of normal installation. The small duct diameter on the
boiler required a special installation and included routine removal and rinsing of the probe liner and sampling line,
which is not typically performed after each sampling period.
