title: Gas chromatographic measurement of carbon monoxide in hydrocarbon matrices with a redox chemiluminescence detector.
abstract: The rapid measurement of trace levels of carbon monoxide in ethylene by gas chromatography with redox chemiluminescence detection is described. Linear response for carbon monoxide over three decades and a detection limit in the sub-parts per million by volume (ppmv) concentration range were observed without methanation or preconcentration of the sample. Samples containing 0.2 ppmv of carbon monoxide in ethylene were readily quantitated.
