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.
痕量气体分析为我们深入了解环境过程提供了广泛的视角，尤其是在全球变暖和空气质量方面。鉴于我们急需识别污染源并精确测量对地球有害的排放物，激光差分光谱（LDS）技术提供了一种独特的方法。该技术通过对光的差分相位测量来测量光的分子的光学分散，并在中红外波段运行，可提供高灵敏度和高稳定性的测量。因此，即使在雨、雾、雪或灰尘等恶劣环境条件下，也能进行非常精确的实时气体测量。该技术可用于抽取式和开放光路两种形式，实际应用包括对油气田的排放监测、测量农业活动的影响以及监测碳捕集存储设施。
