ABSTRACT:
A method of detecting a component gas of a gaseous mixture, and apparatus implementing the method, is disclosed. The method includes passing the mixture through a fixed-phase separator to produce an effluent in which the components are consigned, in ordered [time-related] fashion, to predetermined portions of the effluent. That portion of the effluent containing the component gas to be detected is monitored to produce a measurement indicative of the quantity of the component gas in the mixture.
