Advances in Accuracy in Supreme Line NOx Analyzers

tom • February 21, 2017

The CLD 811 Supreme line NOx analyzer is now sensitive to 1 ppb! Continuous development work has resulted in this improvement over the previous detection limit of 10 ppb. Now, with a range from 10,000 ppm to 1 ppb, this instrument covers an amazing range of seven decades. No other instrument can match this dynamic range. Coupled with the built in computer for data collection and storage, this is the ultimate research analyzer. Provided with a heated sample inlet and bypass regulator, the CLD 811 is equipped to handle raw exhaust samples in high concentrations while keeping the sensitivity necessary to handle diluted bag samples where NOx concentrations may be very low.

ECO PHYSICS recently visited the NASA Glenn Research Center in Cleveland, Ohio. Glenn is NASA’s only research center in the Midwest, officially named after John Glenn in March 1999. This site was established in 1941 and was incorporated into NASA in 1958. It is NASA’s third oldest research center. The purpose of the facility has evolved over the years, it was originally for aircraft propulsion studies and now it creates advanced technology for aviation and space exploration. Their facilities currently include wind tunnels, drop towers, vacuum chambers, and a research aircraft hangar. We were fortunate enough to see some of these and take some photos during our installation and training visit. Glenn is involved with many important projects, such as the International Space Station and the Artemis Program, which is NASA’s latest plan to return to the Moon. We hope to be involved in more of the great work and research that NASA Glenn will do in the future. Thank you to Krystal and Dawn for their time.
