Laser Spectroscopy Gas Detector

Detecting toxic or flammable gases in industrial settings like mines, or oil and gas refineries, can be a matter of life and death. Currently portable detectors that are commonly used are electrochemical-based, with a chemical reaction occurring between the gas and a thin metallic film in the detector.

Photonic Innovations, a spin-out company from the University of Otago, is commercialising a gas detector which uses laser spectroscopy. The technology was initially developed by Andrew Wilson and relies on the fact that each gas has a unique “signature” that can be detected in the beam of a laser....
