  • Process for determining amount of argon contamination in oxygen and related apparatus therefor
    Patent number: 5762686
    Abstract: A process for determining the amount of argon contamination present in high purity oxygen employing a combination apparatus including a gas chromatography apparatus, a pressure swing adsorption apparatus, and a conduit connecting the two apparatus to each other. The gas chromatography apparatus can be run with its column at about 70.degree. F. (21.1.degree. C.) or higher. A sample of the high purity oxygen is fed to the pressure swing adsorption apparatus, where a portion of the oxygen is removed, and then the thus modified sample is fed through the conduit to the gas chromatography apparatus. Since some of the oxygen has been removed with the pressure swing adsorption apparatus, the graph generated by the gas chromatography apparatus shows 2 resolved peaks, namely a small argon peak preceding a large oxygen peak, even though the column of the gas chromatography apparatus is not being cooled to cryogenic temperatures with a cryogen.
