HazardEx - Detecting Hydrogen Gas and Flames

2011-7-5 · The partner to gas detection is flame detection. Hydrogen presents several flame-detection challenges. Hydrogen burns a very pale blue to nearly invisible flame. Technologies to detect hydrogen flames include flame detectors that sense the non-visible spectrum of electromagnetic radiation, which includes ultraviolet (UV) and IR radiation.

Highly selective and rapidly responsive fluorescent …

A new fluorescent probe 6-(2, 4-dinitrophenoxy)-2-naphthonitrile (probe 1) was designed and synthesized for the selective detection of hydrogen sulfide (H 2 S). The addition of H 2 S to a solution of probe 1 resulted in a marked fluorescence turn-on alongside a visual color change from colorless to light yellow. Importantly, this distinct color response indied that probe 1 could be used as
