Tunable Diode Laser Absorption Spectroscopy (TDLAS) has evolved over the past decade from a laboratory specialty to an accepted, robust, and reliable technology for trace gas sensing. Some applications include improving efficiency of gas leak detection surveying, monitoring and controlling trace gases in chemical and pharmaceutical processing, and monitoring emissions in energy production plants. The recent advent of lightweight battery-powered standoff TDLAS sensors is enabling novel applications for remote gas sensing and non-contact process monitoring. This paper provides an overview of these next-generation TDLAS tools.
