• Description:
  Advantages of ion mobility spectrometry (IMS) in the real time detection of aniline (62533) were discussed. In order to characterize IMS behavior as an effluent sensor, a flow injection IMS device was evaluated in which an IMS was used as a detector for a heated injector port. An IMS drift tube was used with an acetone doped reaction region and a membrane inlet. Five microliter replicate samples were introduced and vaporized in the inlet in 15 to 90 second intervals and drawn into the IMS. Detection limits were about 0.5 milligrams/liter for 5 microliter aliquots. Sampling intervals could be reduced to 15 seconds for all concentrations below 40 micrograms/liter above which a working range could be considered to approximately 100 milligrams/liter. Four solvents were evaluated as interferences. All affected the peak area for aniline, although the causes arose through different mechanisms. The authors conclude that the use of IMS as a flow sensor for aniline in organic solvents should be restricted at present to samples free of compounds with strong proton affinities and solvents which do not exhibit strong dipoles.
