Abstract
An apparatus for measuring the composition of a gas mixture containing known components, including a first gas density sensor configured and arranged to measure the density of a first mixture made by combining a gaseous first component and a gaseous second component; a second gas density sensor configured and arranged to measure the density of a second mixture made by combining the first mixture with a gaseous third component; and a processor programmed to determined based on data from the first gas density sensor the relative compositions of the first component and the second component in the first mixture, and to determine based on the data from the second gas density sensor the relative compositions of the first mixture and the third component in the second mixture, and thus to determine the relative compositions of the first component, the second component, and the third component in the second mixture.
