摘要
采用带转化炉的氢火焰气相色谱与色谱工作站,通过选择合适的操作条件及标准气体样品,对工业用乙烯、丙烯中痕量的一氧化碳、二氧化碳进行检测,方法的检出限达到μL/m3级水平。对方法的回收率及精密度作试验,测定回收率为97.1%—103.9%,相对标准偏差（n=6）为2.67%~7.40%。
The paper inrtoduces determining the trace amount of carbon monoxide and carbon dioxide in the industrial ethylene and propylene by the hydrogen flame gas chromatography and standard gas chromatography workstation,and by choosing the appropriate operating condition.Its pick up limit achieves the μl/m3 level.The every recovery is in the range 97.1%——103.9% with the lelative standard deviation 2.67%——7.40%.
