The author describes an improved method for the simultaneous and rapid estimation of oxygen and sulphur in tough-pitch copper. The main past of appartus is similar to that used in the determination of oxygen in iron and steel, which had been established by the Nippon Gakuzyutsu Shinko Kai. Only the H2S absorbing tower is attached to the improved method. According to current methods, the two elements are deter mined individually, and the determination of sulphur takes so long a time as 6 days. On the contrary, the improved method can determine oxygen and sulphur at the same time in 2 hours. The errors by the improved method are not greater than the usual method.
