Abstract

134,243. Rideal, E. K., and Taylor, H. S. June 4, 1918. Gas analysis.-The amount of carbon monoxide present in hydrogen, or in the atmosphere of coal mines &c., is measured by causing it to combine with added oxygen to form carbon dioxide by passage over a a catalyst, absorbing the carbon dioxide in lime-water, and measuring the amount absorbed by the variation in the electrical conductivity of the lime-water. The oxygen may be supplied by adding air, or the mixture of hydrogen and oxygen obtained from an electrolytic cell. The gas to be tested, freed from carbon dioxide and sulphuretted hydrogen by passage through caustic soda solution or otherwise, is passed through a meter d, electrolytic gas from a cell e is added, and the mixture passed through a chamber a containing iron-chromium-cerium oxide catalyst maintained at 200-250‹ C. by an electric heating-coil b. The gas is passed through a spiral bubbler or a glass-wool column g, down which lime-water flows at a regulated speed, and from which it passes to a cell h, in which its conductivity is measured. The variation in conductivity may be recorded by an instrument i. The apparatus may be used to measure the amount of any constituent of a gas which, by fractional combustion with added air or oxygen, will yield a gas which can be absorbed by a liquid, the conductivity of which varies with the amount of absorbed gas.
