Method and apparatus for detecting halogen group gas
Abstract
Abstract A METHOD OF DETECTING CHLORINE GAS ENTAILS MIXING COPPER PARTICLES WITH A SILVER ACTIVATED BLUE PHOSPHOR COMPOUND AND EXPOSING THIS MIXTURE TO AN ENVIROMENT SUSPECTED OF CONTAINING CHLORINE GAS TO CONVERT A PORTION OF THE COPPER TO COPPER CHLORIDE. THE EXPOSED MIXTURE IS REACTED BY HEATING IT TO A TEMPERATURE SUFFICIENT TO CAUSE THE COPPER CHLORIDE TO ACCELERATE DIFFUSION OF COPPER ATOMS INTO THE CRYSTAL LATTICE NETWORK OF THE PHOSPHOR. THE REACTED MIXTURE IS EXCITED WITH A SOURCE OF RADIANT ENERGY AND THE SPECTRAL EMMISION OF THE REACTED MIXTURE IS THEN DETECTED AND COMPARED WITH THE SPECTRAL EMMISION OF THE BLUE PHOSPHOR COMPOUND TO DETERMINE IF A SHIFT IN SPECTRAL EMISSION, WHICH IS INDICATIVE OF THE PRESENCE OF CHLORINE, HAS OCCURED.
