Abstract:

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.
