1529. ---------------. [I. G. FARBENINDUSTRIE A.-G.] [Supervision of the Purity of Oxygen and Nitrogen Produced by the Liquefaction of Air.] TOM Reel 195, Part 10, Item 3, Frames 31,234-31,246, 1939.
Description of a new method, based on the heat conductivity of O2 and N2, by which impurities of even 0.1% can be detected rapidly and efficiently. Several tables and graphs are included, depicting the effect of various phenomena encountered in the determination of impurities on the sensitivity of the measuring apparatus.
