    The principles of the bromination-carbon reduction method for determining oxygen in metals are discussed. A simplified apparatus and an improved procedure are described and the effect of certain variables is considered. The optimum temperature for the bromination reaction is approximately 900 C. At temperatures considerably less or greater, the reaction is slower. The use of bromine free from organic compounds is desirable. Graphite, platinum, or gold boats may be used. The method has been applied to the determination of oxygen in titanium, zirconium, chromium, vanadium, steels, and other metals. It is not applicable to steels containing oxide inclusions.
