Our core business structure is focused on:

1. 1) The development of methods to measure trace elements utilizing X-ray Fluorescence (XRF)
2. 2) The manufacture of instruments for monitoring emission and ambient concentrations of metals
3. 3) Quantitative aerosol generation for auditing and calibrating source and ambient monitors
4. 4) Environmental consulting, with a focus on receptor modeling, chemical mass balance and source apportionment
5. 5) Analytical services involving XRF analysis of elemental deposits on air filters

1) CES prides itself in accepting client’s unique technical challenges and providing them with results through our innovated technical solutions. Today 50% of our recent method development projects do employ X-ray Fluorescence for trace metals analysis. However, we continue to be active in the method develop of aerosol generation, fugitive emissions sampling and plume simulation.

Our method development capabilities have been recognized by the U.S. EPA with a Small Business Innovative Research (SBIR) award to study performance of the Xact 640 CEMS at a coal-fired power plant. Some of our other clients who have utilized our method development qualifications are the Electric Power Research Institute, U. S. Army, U. S. Army Corp of Engineers, Eli Lilly Company, Doe Run Company, Midwest Research Institute, Idaho Department of Environmental Quality, and the American Petroleum Institute. CES has commercialized the most promising methods that we have developed to date, which has given rise to our current product list.

2) CES was the first and is the only commercial manufacture of XRF based multi-metals CEMS in the world. The development of this technology earned CES the U.S. EPA’s Clean Air Excellence Award in 2007 as we offered our third generation of this ground breaking instrument the Xact 640.

After achieving success in the emissions monitoring field CES applied its CEMS knowledge toward the ambient market. Currently, our ambient and emissions monitors are used by clients in both private industry and government agencies around the world. The following are a few of our instrument owners: Canada Ministry of Environment, U. S. Army, Missouri Department of Natural Resources, Queensland Australia Environmental Protection Agency, Electric Power Research Institute, U. S. Army Corp of Engineers, Evonik Industries AG, South Korea National Institute of Environmental Research, Eli Lilly Company and U. S. Navy

3) In an effort to validate the extraordinary accuracy and precision of the Xact 640, we developed and received EPA approval for a Quantitative Aerosol Generator (QAG 820). The QAG 820 average relative accuracy and precision of its multi-metal aerosol emissions is better than 95%.

The QAG 820 has been used for five years to perform annual relative accuracy test audit (RATA) of the Xact 640’s. The capability to produce an accurate and stable aerosol concentration has allowed CES to expand the use of the technology to calibrating and validating any metals or particulate matter monitors.

Recently several state and local regulatory enforcement agencies have begun to require the use of PM CEMS on power generation facilities. This actuality has increased the interest of power generation companies in CESs’ ability to calibrate and audit emissions monitors. We therefore have begun development a particulate matter Quantitative Aerosol Generator (PM QAG) to meet the needs of clients operating either a light scattering or Beta-attenuation PM CEMS.

The objective of the PM QAG is to provide PM CEMS manufactures and operators with a user-friendly method of calibrate and auditing their instruments. This will dramatically reduce the costs and difficulty associated with performing a PS-11. We have also designed the PM QAG to have a greater dynamic spiking range, which will allow for proper compliance assessments of PM CEMS.

4) CES consulting specializes in innovative solutions to air quality problems by using source apportionment and chemical mass balance receptor modeling. Whether the study is part of a State Implementation Plan (SIP) or a lead smelter ambient monitoring study, CES can develop the sampling protocols, procure the equipment, organize the monitoring, and complete the study. These techniques allow CES to locate and prioritize in order of percent contribution at the receptor (ambient monitor) the metal emissions based on the unique chemical profiles of each individual source. The relative apportionment of onsite chemical species between potential sources is based on a statistical comparison of the chemical profile or “fingerprint” of each individual source within the overall chemical profile of any given ambient sample.

Our personnel use the latest CMB software (CMB-8.2) in our modeling and have directed more than 100 airshed source apportionment studies in the U.S., Mexico, Canada, and Brazil. We have preformed studies for the U.S. EPA, California’s South Coast Air Basin and numerous copper and lead smelters throughout the world. Our staffs routinely teach short courses on receptor modeling and chemical mass balance transfer the operation of the model to the client’s staff.

5) CES is committed to providing high quality, competitively priced analytical results with rapid turn-around-times. Our detection limits are extremely low and all results are NIST traceable. We employ X-ray Fluorescence (XRF) as our primary analytical technique to quantify the metals deposited on air monitoring filters. This is the same non-destructive procedure used by the U.S. EPA in its PM2.5 filter project. Our quality control and assurance procedures are performed in accordance with EPA Compendium Method IO-3.3: For the Determination of Metals in Ambient Particulate Matter Using X-Ray Fluorescence (XRF) Spectroscopy. The technique is generally applicable to elements with atomic numbers ranging from 13 (Al) to 92 (U).
