• A set of air samples often contains large ranges of concentrations. Enthalpy is equipped to recognize and appropriately handle these wide ranges.
• Air test methods often require triplicate injections. Air quality labs are aware of this and treat it as standard practice. The triplicate injection requirement for both calibration gases and sample gases can increase the rates for air analyses.
• Air quality labs must maintain a very well developed quality system compared to other types of environmental labs. Because air matrices tend to be varied and complex, the amount of QA input for each sample is typically greater than for a water effluent or IH type lab. Enthalpy understands this and, as a result, has 1 QA person for every 3.5 analysts, and 1 report writer for every 4 analysts.
• EPA guidance and state regulations require a very detailed report. Enthalpy reports every bit of information any reviewer would need to reproduce our results. These reports often are hundreds and even thousands of pages. In addition, we take the time to compile and double-check all these data. While stack test reports often may get through agencies with only summary analytical data as an appendix, it's not unusual for the agency to request all appropriate documentation when questions about the results arise. To ensure a seamless process, we include up front all data for review.
• Enthalpy has over 65 man-years of stack testing experience in the field. Many of Enthalpy's senior environmental staff are ex-stack testers with extensive experience performing on-site sample collection and analysis for most EPA air test methods. This experience is invaluable because different industries, source types or target analytes can exhibit unique or unexpected issues at any point in a testing project.
• Enthalpy specializes in EPA Method 18 analysis. Our owners have performed and analyzed Method 18 for 18 years, making our lab the most experienced and knowledgeable in the industry. Many of Enthalpy's top people have more than 10 years of experience dealing with M18 projects. We process hundreds of M18 samples each and every month.
