Reëxamination of the Unterzaucher method as a new determination for organic oxygen was carried out by the use of a platinum-carbon, prepared by the authors' own method, and with the temperature of the carbon-contact furnace lowered to 950°. Analyses of substances consisting of carbon, hydrogen, nitrogen, and oxygen, as well as those containing halogen or sulfur gave good results. The decreased size of the apparatus and simplification of the procedure made it possible to determine oxygen directly and just as easily as the analyses of other elements, in equal accuracy.
