More Information
Summary:A method and apparatus for a gas detection system comprises a sample cell containing at least one aperture and a substrate. The substrate comprises a chemiluminescent material that produces photons upon exposure to a fluorine-containing compound. A photo-detector is positioned to receive at least a portion of the photons, wherein the photo-detector generates an electrical output signal relating to a concentration of the fluorine-containing compound.
