本文采用快离子轰击质谱(FIBMS)技术分别选用甘油、S-甘油和间硝基苄醇做底物,对五种环状芳香低聚物进行分析,确定了几种不同大小的芳香环状低聚物的存在,并同时给出了各种不同聚合度组分的相对含量.实验证明,质谱是分析环状低聚物的快速、有效的方法.
In this paper, five kinds of cyclic aromatic oligomers were analyzed by fast ion bombardment mass spectrometry (FIBMS) using glycerol, S-glycerol and m-nitrobenzyl alcohol as substrates, respectively. Several aromatic ring-shaped The existence of polymer and the relative content of different polymerization degree components are also demonstrated.Experiments show that mass spectrometry is a fast and effective method for the analysis of cyclic oligomers.
