Article Published in Emerging Topics in Life Sciences Journal

November 8, 2021

We are pleased to announce that we recently had an article published in the Emerging Topics in Life Sciences Journal on “Trace gas analysis with laser dispersion spectroscopy”.

The article covers how our Laser Dispersion Spectroscopy (LDS) technology can be used for trace gas analysis, such as accurately identifying and measuring methane, along with other greenhouse gasses.

You can read the abstract below:

“Trace gas analysis provides a wide range of insights into environmental processes, particularly with regards to global warming and air quality. With the urgent need to identify sources and accurately measure the harmful emissions negatively impacting our planet, Laser Dispersion Spectroscopy (LDS) offers a unique approach. LDS technology measures optical molecular dispersion via a differential phase measurement of light and, operating in the mid-infrared, provides highly sensitive and robust measurements. This enables highly precise, real-time gas measurements even in adverse environmental conditions such as rain, fog, snow or dust. The technology can be used in both extractive and open-path formats, with real-world applications including emissions monitoring on oil and gas sites, measuring the impact of agricultural activities and monitoring carbon capture storage facilities.”
