| 中文摘要: |
| 目前，国内尚没有同时分析水泥助磨剂中多个醇胺类的方法标准。采用气相色谱法同时检测水泥助磨剂中二乙二醇、二乙醇单异丙醇胺、三异丙醇胺（含同分异构体）、三乙醇胺含量多个醇胺类，经过多次对比试验，选择RBX-WAX石英毛细管柱，确定了最佳色谱条件及样品处理方法，该方法具有分离完全、精密度及重现性高等优点。 |
| 英文摘要: |
| At present, there is no method standard for simultaneous analysis of multiple alcohol amines in cement grinding aids in China. The content of diethylene glycol, diethanol monoisopropanolamine, triisopropanolamine (including isomers) and triethanolamine in cement grinding aids were determined by gas chromatography. After many comparative tests, rbx-wax quartz capillary column was selected to determine the optimal chromatographic conditions and sample processing method. This method has the advantages of complete separation, high precision and reproducibility. |
