Gas Analysis with TDLAS in Low-Light Transmission Environments: Versatility and Applications

June 15, 2023

Gas analysis plays a crucial role in various industries and segments to monitor and ensure a safe working environment and optimize production processes. In low-light transmission environments where other techniques may be limited, gas analysis with Tunable Diode Laser Absorption Spectroscopy (TDLAS) offers a powerful and versatile solution. Let’s explore the possibilities of TDLAS in such environments and examine examples of industries where this technology can be useful.

Possibilities with TDLAS in Low-Light Transmission Environments:

Methane gas detection in the mining industry: Ore mines and coal mines can have high dust levels and limited light transmission. Here, TDLAS technology can be used to measure methane gas concentrations and monitor potentially explosive environments in real-time.

Flue gas analysis in the process industry: Process plants and refineries can generate flue gases with high levels of particles and contaminants. TDLAS enables accurate and rapid measurement of gases such as sulfur dioxide, nitrogen oxides, and carbon dioxide, even in low-light transmission environments.

Biogas plants and waste treatment: In biogas production facilities and waste treatment plants, the atmosphere can be rich in methane and other gases. TDLAS technology offers a reliable method to monitor and control gas flows and optimize the processes.

Laboratory applications: In scientific laboratories, TDLAS can be used to measure gases in low-light transmission environments. This can be applicable in various research areas such as climate science, materials science, and chemistry.

Offshore and marine industry: In marine and offshore environments, TDLAS technology can be used to measure gases on board ships, platforms, or underwater. Its ability to work in low-light transmission environments enables monitoring of gas emissions and protection of the environment.


Gas analysis with TDLAS offers significant advantages in low-light transmission environments, where other techniques may be limited. With its high accuracy, fast measurements, and ability to work in such environments, TDLAS proves to be a valuable tool for gas analysis in industries ranging from mining and process plants to biogas facilities and marine applications.
