    摘要: A method and system for analyzing gas concentration by measuring the steady state pressure in a dual membrane cell. A first membrane is exposed to a test gas and a second membrane to a reference gas where the first and second membranes have differing permeabilities. The test gas and the reference gas continuously counterdiffuse through the membranes and the steady state pressure in the intermembrane space is directly proportional to the gas concentration of the test gas component.
