摘要：

The response of a capillary column gas chromatograph/ion mobility spectrometer (GC/IMS) system to chlorinated and brominated alkanes and alkenes in nitrogen, air and nitrogen/CO2 mixtures was studied. Product ions were formed through dissociative electron capture processes or charge transfer reactions, yielding chloride or bromide ions. The quantitative response was shown to depend on the composition of the carrier gas in which atmospheric pressure ionization processes occurred as well as on the IMS cell temperature. Large variations in the quantitative response of the GC/IMS to different halogenated compounds were observed. The results were compared to those reported for the doped electron capture detector (ECD). Practical implications of the GC/IMS system as a monitor and detector for halogenated aliphatic compounds are discussed.
