Abstract

160,930. Davis, R. H., and Resling, C. Dec. 30, 1919. Gas analysis. - Apparatus for analyzing gases comprises a receptacle a containing an absorbent for the constituent to be determined, the ends of the vessel being closed by diaphragms e, e<1>, the first connected to a pressure-device and the other diaphragm designed to be adjusted in position as by a screw h and nut i so as to control the inlet and exit of gas through a valve n. In use, a negative pressure is produced in the vessel by distending the diaphragm e<1>, until the pointer makes a complete revolution: the valve n is then momentarily opened to admit a sample of gas; the final pressure shows the proportion of the sample - .absorbed by the reagent; the valve n is then opened and the diaphragm e<1> pressed inwards to discharge the residual gas.
