| Abstract: | This paper described a gas chromatographic method for the analysis of micro amount of methanol in pure dimethyl ether(DME).A Porapak T column(φ2mm×3m) is used in 110℃,The sample is injected directly in liquid phase and with liquid external standard;N 2 is used as carrier gas;and FID detector is employed. The results show that the recovery is 100 0%～100 2% and the relative standard deviation is less than ±6%.This method is simple,accurate and useful for controlling the quality of pure DME products. |
