摘要
采用裂解同时烷基化气相色谱-质谱联用技术对不同类型的环氧酯树脂进行分析研究(SPM-GC-MS)。以衍生化试剂四甲基氢氧化胺与样品同时入射,经高效毛细管气相色谱分离,质谱检测,可鉴定不同类型环氧酯树脂结构。较直接裂解-气相色谱-质谱联用技术,快速、准确、谱图直观、灵敏度高。
Several different types of epoxy ester resins have been analyzed by simultaneous pyrolysis mcthylation gas chromatography-mass spectrometry (SPM-GC-MS). The sample mixed with tetram-ethylammonium hydroxide, and the process including simultaneous pryolysis derivatiration and mass spectrometry determination. This method is sensitive, accurate, convenient, and involves minimal sample manipulation.
