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.
本文描述了采用氧化还原化学发光检测的气相色谱法快速测定乙烯中痕量一氧化碳的方法。在无需对样品进行甲烷化或预浓缩的情况下，观察到一氧化碳在三个数量级上呈线性响应，且在体积分数百万分比（ppmv）浓度范围内具有检测限。含有0.2 ppmv一氧化碳的乙烯样品能够轻松实现定量分析。
