【摘要】 本文采用毛细管气相色谱法实现了对工业品甲基丙烯酸甲酯(MMA)及其杂质的高效分离,检测出29个组份.通过标样对照和色质联用色谱图解析,确定了24种组份,并用内标法和面积归一化法给出了精确定量.该方法相对偏差为0.0158.更多还原

【Abstract】 A higher-efficient separation of MMA (tech.)and its impurities was realised by a new capillary gas chromatography at the programming temperature. 29 components were examined. 24 components of them were identified by means of several standard samples and the analysis of diagrams obtained by GC/MS. The results of quantitive analysis and the higher precision (r=0.0158) wer obtained in this work.更多还原
