The solution
The SERVOTOUGH Laser 3 Plus Environmental for ammonia is typically used in DeNOx and emission measurement applications. However, in this application it was optimized to measure very low levels of ammonia, down to 0.2 ppm, across very short optical pathlengths. This is a perfect application for a laser-based measurement solution, demanding a high degree of measurement sensitivity and stability.
The results
Over the initial trial period, Servomex demonstrated that the Laser 3 Plus Environmental was more stable and reliable when compared to competitor products, which were installed side-by-side for comparison.
This will ultimately result in the semiconductor plant installing 17 cross-stack analyzers, and removing the need for complex heated measurements, sample systems and transport tubing.
Over an extended period, the Laser 3 Plus installations were compared to an extractive standard technique where samples were taken over a fixed time and analyzed at an independent laboratory. The Laser 3 Plus demonstrated excellent correlation to the standard technique, leading to an EPA QAL 2 equivalence approval for the installation.
Further expectations are for the cross-stack NH 3 emission laser measurement to become standard, not only within the other plants from the same manufacturer, but also within the global semiconductor industry.
