A chromatography with double valve dual channel and double hydrogen flame detector was used to analyze amounts of carbon monoxide, carbon dioxide and hydrocarbon impurities in ethylene by inserting sample once. Influence of the carrier gas flow rate, column temperature, heating rate, split ratio on the determining result was investigated,the optimum conditions were obtained. At the same time,the precision, accuracy and minimum limit of the detection method were analyzed. The results show that the method is simple, fast, accurate and reliable.
