建立测定氯氟吡氧乙酸十二酯含量的气相色谱(外标法)检测方法。色谱柱为二甲基聚硅氧烷毛细管柱(0．53mm×30m×1μm)；柱温：初始150℃,保持3min,30℃·min-1,程序升温至270℃,保持10min；气化室温度：280℃；检测器温度：280℃；载气为氮气。测定的RSD为0．60%,回收率在95．92%~103．72%之间,线性相关系数为0．9992。该本系操作方便、快速,结果有较好重现性,能达到含量测定目的。%A method for determination of Fluroxypyr-dodecyl is established using gas chromatography with external standard meth-od. Gas chromatography Dimethylpolysiloxane capillary column(0. 53mm×30m×1μm);Column temperature:the initial temperature was kept at 150℃ for 3min,with a temperature rising rate at 30℃·min-1 ,terminal temperature was kept at 270℃ for 10min;tem-perature of aerification room:280℃;temperature of detector:280℃. The standard derivation is 454,RSD is 0. 60%,recovery is 95. 92 to 103. 72%,and liner correlation coefficient is 0. 9992. This method is quick,accurate,and operating simple. Reappearing the nature is good. It’s suitable in the quantitative determination of dodecane chloroacetate.
