摘要
通过恒温水浴完全气化样品,建立了用毛细管气相色谱法测定液化石油气中二甲醚含量的方法。采用PLOT/Q(30 m×0.53 mm×40μm)毛细管柱,以热导池检测器检测,氦气为载气,以面积校正归一化法计算二甲醚含量。结果表明,该方法操作简单,实用性强,重复性好,可以用于液化石油气中二甲醚含量的分析。
A method was developed for the detection of the dimethyl ether in the liquefied petroleum gas by constant temperature water bath gasification sampling and capillary gas chromatography with TCD detector and PLOT/Q（30m×0.53mm×40μm）capillary column.Helium was used as carrier gas and area normalization method was applied to calculate the content of the dimethyl ether.The result showed that the method was easy to operate and practical with good accuracy and repeatability,and can be used for the analysis of the dimethyl ether in liquefied petroleum.
