An apparatus for the automatic control of toe pyrolysis in the airect determination of oxygen was proposed. The apparatus was composed from a fine capillary and a monometer, which contained 33% KOH soln. and had two electrodes (Fig. 1). The electrodes were connected to a vacuum-tube-relay so as to stop the motion of the moving furnace whenever the pressure in the reaction tube was raised, i.e. when the temp. of the furnace was rising, and when the sample began to boil or decompose. CuO-furnace for the oxidation of CO was separated from the main furnace to prevent the errors caused by the water produced by the oxidation of H2. Standard deviations obtained from the result of an experiment using this apparatus were 0.34_??_0.45% (Table. 1). The main cause of these deviations to be due to the fluctuation of the blank values (Table 2), which depended upon the temp. of the main furnace.
