Lab Analysis Services

Clean Air Engineering Laboratory Services puts to use its over 40 years of experience in testing and analysis to provide the best data and help you understand what it means. We use the most stringent quality control parameters in the industry to ensure that our report provides you with the correct numbers the first time.

Clean Air Engineering Laboratory Services has over 4 decades of experience in filterable particulate matter (FPM) and condensable particulate matter (CPM) analysis. We use advanced anti static measures and the most stringent quality controls in the industry including a calculated detection limit to help make sure what we weigh is your sample. After your project is done, we can use our expertise to further help you understand your samples beyond the weight to the meaning behind it so you can get the most out of one weight.

A combination of laboratory test and computer modeling, using industry leading methods and equipment, allows either direct measurement and/or prediction of pertinent information. The data we generate can be of great interest to the engineering and operational staff of a utility. The information allows them to determine whether the fly ash produced from a given coal will be compatible with their control device.

Clean Air Engineering Laboratory Services puts to use its over 40 years of experience in testing and analysis to provide the best data and help you understand what it means. We use the most stringent quality control parameters in the industry, including all EPA Method 18 requirements, to ensure that our report provides you with the correct numbers the first time.

Clean Air Engineering Laboratory Services uses its famous Mercury monitoring knowledge to efficiently analyze a wide range of sorbent tube concentrations with state of the art certified instrumentation. After the analysis we can help with understanding the data and troubleshooting if necessary to help make your project a success.

EPA Methods 6/8 similarly require a barium-thorin titrimetric analysis. EPA Method 8 is currently the only method that EPA has promulgated for measuring sulfuric acid and sulfur trioxide emissions. CleanAir Engineering has modified the analysis by slightly acidifying the isopropanol. The addition of trace amounts of acid (0.1 mL of 0.1 N HCl per 4L of isopropanol) prevents a negative blank sample. The same acidified isopropanol is used for analyzing all standards and samples.

Most particle collection devices are sized using Stokes’ particle size distribution data. For in-situ devices, the aerodynamic particle size is determined. Many laboratory techniques will determine particle size indirectly from direct measurements of some parameter other than the complete geometry, or diameter. A Stokes’ size distribution can be generated using data from a Bahco™ Centrifugal Classifier. The Bahco is the particle sizing device recommended by the Industrial Gas Cleaning Institute to determine particle size and collection efficiency of mechanical collectors. It was also the device used to gather data for the Electric Power Research Institute’s Electrostatic Precipitator Model (ESP Computer Model). Operation and calibration of the Bahco™ is described in the American Society of Mechanical Engineers Power Test Code 28.

Clean Air has over 40 years of experience in analyzing these samples using industry standard “wet methods”. We perform a stringent quality assurance program along with samples (including sample spikes and duplicates) to ensure the data we provide is correct and reproducible. Flue Gas Desulfurization (FGD) is a general term which applies to any chemical process used to remove SO2 from combustion flue gases. Most FGD processes operate by contacting the flue gases with an alkaline slurry or solution that absorbs and subsequently reacts with the acidic SO2. Wet, calcium-based processes – those which use lime (CaO) or limestone (CaCO3) as the alkaline reagent – are the most commonly used FGD processes in utility applications. In these processes, SO2 absorbed from the flue gas reacts with the alkaline species in the scrubbing liquor to form relatively insoluble calcium sulfite and/or calcium sulfate solids. Many FGDs produce by-product gypsum for use as a raw material in other manufacturing processes. FGD performance evaluation can involve acquisition of samples from various points in the FGD process. Liquid and solids samples are usually acquired from the following points:

EPA Method 24 is the only method commonly accepted by EPA and U.S. state/local regulatory bodies for the measurement of volatile organic compound (VOC) content in paints, inks, and related coating products. The method is used by many manufacturing industries for reporting emissions of coating and related products to local regulatory bodies, with some of the most common being the CASE industries (coatings, adhesives, sealants, and elastomers). This includes both coating manufacturers and coating operations, such as automotive, appliance, furniture and can lining manufacturers.
