摘要
应用基质辅助激光解吸电离飞行时间质谱 ( MALDI- TOF- MS)技术对系列环状预聚体进行了表征 ,分别确定了系列环状预聚体各自不同的聚合度 ,同时对它们的结构进行了确认 ,获得了满意的结果。实验结果表明 MALDI- TOF- MS是分析环状预聚体准确。
A series of macrocylic oligomers were successfully characterized by matrix assisted laser desorption ionization time of flight mass (MALDI TOF MS) technique. The different degrees of polymerization of macrocylic oligomers were determined, and their structures were affirmed at the same time. The experiment results indicate that MALDI TOF MS is an accurate, rapid tool for the analysis of macrocylic oligomers.
