摘　　要：利用傅里叶变换离子回旋共振质谱 (FT ICR MS) ,分析了两类复杂的离子型表面活性剂样品。实验结果表明 :高分辨FT ICR MS ,可以简单、快速、准确地获得两类化合物的结构信息 ,利用其高准确度的质量测定数据 ,计算出复杂样品中各组分的元素组成 ,鉴定出具体化合物 ,显示了FT ICRFourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) was used for the analysis of two kinds of complicated surfactant sample. It has been shown from the experimental results that the structural information of two kinds of compound can be simply,rapidly and accurately obtained by the high resolution FT-ICR-MS. Using the high accuracy mass data, measured the elemental compositions of all components in the complicated sample were calculated and all compounds were identified, which showed the powerful capacity of FT-ICR-MS in structural analysis of molecules and identification of unknown samples.
