采用基质辅助激光解吸电离飞行时间质谱（ＮＡＬＤＩ－ＴＯＦ－ＭＳ）技术分别对８个单分散 的聚苯胺齐聚物进行了分析研究。实验结果表明，ＭＡＬＤＩ－ＴＯＦ－ＭＳ不但可以作为分析单分散 聚苯胺齐聚物的直观、准确、快速的分析工具，而且可以为合成路线的确定提供有利的证据。
Eight monodispersed polyaniline oligomers were analyzed by matrix-assisted laser desorption / ionization time of flight mass spectrometry (NALDI-TOF-MS). The experimental results show that MALDI-TOF-MS can not only be an intuitive, accurate and rapid analytical tool for the analysis of monodisperse polyaniline oligomers, but also provide favorable evidence for the determination of synthetic routes.
