THE METHOD OF DETECTING THE PRESENCE OF CONTAMINATING OXYGEN IN A SEALED TRANSPARENT ENVELOPE CONTAINING SOURCES OF TRACES OF CYANOGEN RADICAL (CN) AND ANOTHER EXCITABLE GAS WHICH COMPRISES PRODUCING A GLOW DISCHARGE IN THE ENVELOPE TOFORM EXCITED CYANOGEN RADICAL MOLECULES AND EXCITED MOLECULES OF SAID OTHER GAS, AND MEASURING THE RATIO OF THE SPECTRAL INTENSITY OF THE CYANOGEN RADICAL MOLECULES AT A GIVEN WAVELENGTH TO THE SPECTRAL INTENSITY OF THE MOLECULES OF SAID OTHER GAS AT ANOTHER GIVEN WAVELENGTH TO OBTAIN A SIGNAL INDICATIVE OF THE OXYGEN CONTENT IN SAID ENVELOPE BY VIRTURE OF SUPPRESSION OF THE EMISSION PRODUCED BY THE CYANOGEN RADICAL MOLECULES BY IONIZED OXYGEN.
