摘　　要：采用高场非对称波形离子迁移谱(FAIMS)对二乙醇胺(DEA)进行快速检测分析,以热解析法进样,确定了二乙醇胺的离子特征信号,并与气相色谱-质谱联用仪的检测结果进行了比较.用聚四氟乙烯(PTFE)扩散管进样,控制二乙醇胺样品气(DEA与空气的混合气)浓度,利用FAIMS对不同浓度的二乙醇胺样品气进行检测.通过对离子特征信号进行量化和重复性分析,确定了二乙醇胺样品气的检出限为0.02μg/L,并建立了FAIMS检测二乙醇胺样品气的离子电流强度积分面积与样品气浓度关系曲线.为FAIMS应用于现场快速检测二乙醇胺提供了一定的依据.The field asymmetric ion mobility spectrometry(FAIMS) technique was used for the rapid analysis of diethanolamine( DEA). The ion characteristic signal of DEA was acquired by FAIMS with the direct thermal desorption method for sampling,which was compared with the result of gas chromatograph-mass spectrometer(GC-MS). The concentration of DEA gas was controlled by the polytetrafluoroethene(PTFE) diffusion tube method. The DEA gas samples with different concentrations were detected by FAIMS technique. The dependence of the integrated ion current on DEA gas concentration was obtained,and the limit of detection for DEA gas is 0. 02 μg / L. This study has laid a foundation for the application of FAIMS technique to on-site rapid detection of DEA.
