摘要
采用气相色谱法分析煤基乙二醇中有机杂质,结合气质联用定性法与标准品比照定性法确定有机杂质的种类及出峰位置,比较面积归一化法、外标法与内标法3种定量方法分析有机杂质含量的异同,确定采用简单便捷的面积归一化法。
The organic impurities in coal-based ethylene glycol was analyzed by gas chromatography. Combined with GC – MS qualitative method and standard reference qualitative method to determine the types of organic impurities and the peak position. The similarities and differences were compared by analyzing the organic impurity content with three kinds of quantitative methods area normalization method,external standard method and internal standard method. The simple and convenient area normalization method is determined.
