Each chemical substance has a unique spectral fingerprint according to its chemicalcomposition and molecular structure. The chemical bonds of the atoms in the moleculesabsorb and emit energy and are responsible for the emission/absorption spectra. Whenirradiated with a high energy beam, the chemical bonds absorbs some of the irradiatedenergy and the rest is emitted to the surrounding atmosphere. The SafEye Open PathGas Detector has been designed to detect such emitted energy at various spectral bandsaccording to the target gas. Most of the hydrocarbon gases feature similar infraredspectral peaks, however there are gases that have unique spectral patterns that requirespecial sensors and filters.
A list of flammable gases/liquids with special spectral patterns that require special gasdetector models are listed herein:
