Abstract
This paper describes an improved method for directly measuring low concentrations of carbon monoxide in air. Carbon monoxide reacts with potassium pallado sulfite impregnated on a chemically inert gel contained in sealed glass tubes. Length of discoloration caused by conversion of yellow sulfite to dark brown palladium or its oxide is an exponential function of CO concentration. Data are presented on the measurement of carbon monoxide in air as well as in oxygen-deficient or oxygen-free atmospheres. Applications are given relative to interfering and non-interfering gases and vapors as well as temperature correction data covering range of −50°F to 120°F and ambient pressure correction.Keywords
