Rely on an expert partner for your measurements
Understanding the long term changes in the atmospheric composition as well as the origin of pollutants is critical for predicting the impacts on the world and the people in it. To do this, having comparable results from the various measurement locations around the world is essential. The global scientific community has therefore developed advanced and standardized analytical methods, including isotopic analysis. Isotopic signatures have become useful tools for a more comprehensive understanding of pollution sources. To aid in this essential research, Air Liquide has developed a range of stable ratio reference gases for Atmosphere monitoring analysis. Our Natural Air product features the same specifications as the Natural Air reference gas defined by the World Meteorological Organization (WMO). Air Liquide is the first and only gas supplier to propose a complete standardized offer for stable isotopic analysis globally. With 30+ years of experience in production of specialty gases and applications, as well as strong recognized R&D capabilities, you can trust Air Liquide to ensure product quality, availability and responsiveness.
