Hydrogen detection system for safety, quality control

Researchers in Japan have developed an optimized hydrogen gas measurement using TDLAS technique. It is reportedly able to achieve a detection range of hydrogen gas concentration of 0. 01% to 100%. The group said that it can improve hydrogen safety and in turn, its adoption. Scientists from Japan have developed a novel method for measuring hydrogen gas that employs tunable diode laser absorption spectroscopy (TDLAS) at different pressures and a high-pressure gas cell. TDLAS is widely utilized for gas analysis, but until now it has had difficulties quantifying low concentrations of hydrogen due ...
