At APT, our goal is to compete more on quality than price; this approach seems to be working, with better than 95% of our sales coming from repeat customers - with much of the remaining work representing the forging of new relationships. We pride ourselves on serving clients in a variety of industries, and so we have a wide breadth of services. Here are just a few: Method 30B RATA Testing
APT analysts routinely perrform on-site vapor-phase mercury testing using an Ohio Lumex analyzer. This instrument allows on-site, near real-time results for immediate assessment of mercury emissions and CEMS performance.Method 29 and Ontario Hydro Testing
If isokinetic sampling and/or speciated mercury results are required, the APT laboratory facility in Arvada, Colorado is equipped with a Perkin Elmer CVAAS for rapid in-house results. Quality assured data can be provided in as little as 72 hours. Our analysts regularly analyze third party audit samples to ensure accuracy.'Fast Flow' Multiple-Crew Flow Testing
APT test teams routinely perform "fast-flow" testing, with up to four test crews conducting Method 2F 3-dimensional flow testing on the same stack simultaneously. With one crew per test port, the total time per traverse is easily reduced to the 5-minute minimum allowed by 40 CFR 75. This greatly reduces the costly time spent at reduced loads.Gaseous Pollutant / Diluent Testing
With state-of-the-art instrumentation, APT test teams have performed many hundreds of RATAs. Our direct extractive or dilution extractive systems meet all applicable performance criteria to provide quality assured, on-site results.
