The oxygen content of various inorganic and organic mercury compounds was determined by the Unterzaucher method. The tube filling was modified by packing porous silver at the tail of the tube where mercury vapor was trapped forming silver-mercury amalgam under a relatively low temperature. Organic mercury compounds containing nitrogen, sulfur, and chlorine were determined prebisely. Inorganic mercury compounds which were volatile at the temperature of the sample heater were also determined quantitatively, and mercurous chromate oxygen, except when it was left as chromium oxide, was determined. Total oxygen, however, could not be determined even if carbon powder was added on the sample. Even after the determination of oxygen was repeated about 100 times by the method using platinum carbon, no deterioration of platinum carbon was found.
