Abstract Sulfur hexafluoride (SF 6 ) is widely used as an insulating gas in electrical equipment. The detection of its decomposition products great significance for assessing the operating condition Carbon tetrafluoride (CF 4 a major product SF , and accurate determination content crucial early equipment failures assessment quality. This study explores application plasma emission chromatography analysis trace CF 6. By optimizing chromatographic conditions, efficient sensitive analytical method has been established. experimental results show that when argon carrier gas, limit this low 0.5 ppm, with relative standard deviation (RSD) less than 3%, demonstrating excellent repeatability. Moreover, good linear range (R 2 = 0.998). accuracy reliability have further verified through actual samples. Plasma provides efficient, sensitive, stable new approach it expected to be
