Analytical Research Laboratory
The Analytical Research Laboratory (ARL) provides quality data, flexibility, and rapid turnaround time in support of research activities at the EERC. The laboratory is equipped for routine and specialized analyses of inorganic and organic constituents using laboratory procedures and analytical methods that adhere to nationally and internationally recognized or approved standards and methods put forth by The U.S. Environmental Protection Agency, ASTM International (ASTM), the International Organization for Standardization, Standard Methods, and other organizations. The range of ARL methods and instruments supports the chemical characterization of a variety of environmental and biological sample types, including fossil fuels, biomass, combustion by-products, geologic materials, fine particulate matter, groundwater, wastewater, fish tissue, and plant materials.
The ARL has in place a laboratory management system (LMS) that is authorized and supported by EERC senior managers. LMS is constructed to meet the requirements of ISO/IEC 17025:2005 General requirements for the competence of testing and calibration laboratories
. A laboratory quality manual defines the requirements and the organizational responsibilities for each major element of LMS and references the supporting documents needed to provide a comprehensive laboratory quality assurance program. Compliance with this manual and its supporting documents ensures that the ARL adequately fulfills client requirements; complies with applicable regulations, statutes, and contractual requirements; and follows relevant national/international methods and standards. Analytical methods are routinely monitored for precision and accuracy with certified reference materials from the National Institute of Standards and Technology (NIST), the South African Bureau of Standards, the International Atomic Energy Agency, and other sources. The ARL participates in interlaboratory studies and proficiency programs such as the Coal and Ash Sample Proficiency Exchange™ (CANSPEX™) Program and a NIST/National Voluntary Laboratory Accreditation Program. This participation allows the ARL to demonstrate competence in methods of analysis by comparing analytical results and techniques with other laboratories nationally and internationally.
- Mercury: The ARL plays a major role in the support of mercury
research at the EERC. With several EERC projects focusing on the occurrence and
fate of mercury in combustion systems, as well as the evaluation of mercury control
technologies, the ARL staff has gained considerable experience in mercury chemistry
and analytical techniques for providing precise and accurate data.
- Measurement of hazardous air pollutants (HAPs) from combustion
systems: The ARL supports research at the EERC related to the fate of HAPs in
combustion systems by thoroughly characterizing the fuel, ash by-products, and stack
emissions. Several EERC projects have evaluated the impact of mercury control technologies
on the fate of other inorganic HAPs, which include As, Be, Cd, Co, Cr, Mn, Ni, Pb,
Sb, and Se.
- Solid waste characterization: The toxicity characteristic
leaching procedure (TCLP) and other leaching procedures are employed for determining
the leachability of RCRA (Resource Conservation and Recovery Act) metals.
- Biomass characterization: The ARL employs internationally
accepted sample preparation and analytical methods from ASTM, EN, and ISO for the
determination of major, minor, and trace constituents in biomass materials such as
wood chips, switchgrass, corn stover, and other potential biofuels.
- Biological sample analysis: To support research related
to the health impacts of environmental pollutants, the ARL has capabilities for
the preparation and analysis of biological tissues such as hair, blood, fish, and
Water quality analysis: To support the activities of the EERC Plains CO2
Reduction (PCOR) Partnership, the ARL is testing the quality of water in areas where
large-scale CO2 injection projects are under way. Over 40 parameters
are being tested at each sampling location to help monitor the water quality over the course of the project.
