  • Patent number: 3961895
    Abstract: A component of a gaseous mixture, particularly carbon dioxide, can be measured in extremely small quantities or concentrations, by supporting on a solid surface a thin film of a liquid, e.g. an aqueous solution of barium hydroxide, which reacts with the gaseous component so as substantially to alter the electrical resistance of the solution. The electric resistance of the film is measured between electrodes, before and after exposure to the test gas. The test is much more sensitive than if a confined body of liquid were used as the test solution.
