Your benefits • Non-contact, extractive measurement (TDLAS) enables quick and easy integration into existing plants • Non-destructive in situ Raman analysis minimizes risks and reduces waste • Robust, process-optimized and low-maintenance gas analysis solutions for reliable long-term operation • Very short response times: “data in real time” enables optimized process control without delay • Precise and rapid gas analysis enables continuous process monitoring 24/7 • Better proven repeatability compared to legacy measure ment technologies used in gas applications

An enormous energy transition is underway, with natural gas, biogas, liquefied natural gas (LNG) and hydrogen playing an increasingly important role in achieving net zero carbon dioxide targets. Changes in gas composition and network infrastructure, as well as advances in process auto mation, will increase the need for online gas analysis in the future to ensure safety, process control and gas quality. What we offer Endress+Hauser’s analyzers incorporate the powerful measurement technologies of tunable diode laser absorption spectroscopy (TDLAS), quenched fluores cence (QF) and Raman spectroscopy. These systems feature a unique product design based on decades of ap plication experience. The TDLAS technology reliably detects and measures the concentration of individual gas molecules such as H 2 O, H 2 S, O 2 and CO 2 in process gas streams in a concentration range of just a few ppm. QF is used for ac curate and reliable measurement of oxygen concentration in gas streams. Raman spectroscopy can be used to deter mine the composition of process gases with high accuracy. This includes, for example, determining the composition of hydrogen-rich natural gas mixtures in power station turbines or the calorific value or Wobbe index in liquefied natural gas (LNG) applications.
