Nitrous oxides, are a group of gases primarily composed of nitric oxide (NO) and nitrogen dioxide (NO2). These gases are significant environmental pollutants, produced by high-temperature combustion processes found in vehicle engines, power plants, and various industrial activities. Monitoring nitrous oxides is essential for protecting public health, complying with environmental regulations, and managing and reducing air pollution effectively.
At Signal Group, we provide state-of-the-art NOx analyzers designed for accurate, reliable, and continuous monitoring of these critical pollutants, helping industries meet stringent emission controls and improve air quality.
Nitrous Oxide, or laughing gas, is a relative newcomer to the list of industrial pollutants of concern to regulatory bodies monitoring climate change. It has a stronger greenhouse effect than carbon dioxide and is produced as a by-product of many industrial processes.
The measurement techniques available for this gas are infra-red and electrochemical cell. Both have their limitations. The US EPA have produced guidelines on what they consider to be the reference method for measuring N2O as part of the process of legislating for it to be measured and reported by engine and vehicle manufacturers and other industries. They suggest using an infra-red detector that uses a catalyst to oxidise CO, the strongest interferent.
Non Dispersive Infrared (NDIR) Multi-gas analysers are available in 1, 2, 3, 4 or 5 gas channel configurations, offering high levels of performance and flexibility. Options include CO, CO2, CH4, NO, N2O, SO2, HCl and O2.
With Signal Group’s nitrous oxides analysers, you gain an expert partner in air quality management. Our analysers help you monitor, report, and reduce N2O emissions effectively, ensuring environmental compliance and promoting public health.

Signal Group’s portable heated FID VOC analyser, the S4 SOLAR XPLORE, has made it to the finals of the Instrumentation Excellence Awards, and a team from Signal will be donning their red-carpet attire for a glittering award ceremony that will take place at the Grand Connaught Rooms in London on
Intriguingly, the Signal Group stand will be staffed by gas analysis experts wearing T-shirts saying ‘Ask me about MCERTS!’ It’s too early to say more, but anyone interested in VOC emissions monitoring should head for Stand-L5…if only to try out the detachable tablets. With a heavy focus on technology development,
Researchers at the University of Sheffield are exploring new exhaust aftertreatment systems for heavy-duty engines capable of running on clean, zero-carbon fuels. This 4-year project is funded by an EPSRC grant and supported by the industrial partner Eminox. The project is led by Bill Nimmo, Professor of Energy Engineering and
