Characterization of Explosives using Electrospray Ionization High Resolution Ion Mobility Spectrometry

ESI-HPIMS for Explosives Characterization

ESI-HPIMS for Explosives CharacterizationIn explosives detection applications, both improved sensitivity and resolving power are highly desirable, as IMS-based detection systems are among the most widely used chemical detection methods at airports, high security buildings, customs, and other security checkpoints. Both improved sensitivity and resolving power are highly desirable for these applications. Electrospray ionization – ion mobility spectrometry (ESI-IMS) address several limitations of current explosives trace detection (ETD) systems.

This Application Note Includes:

  • Introduction to Electrospray ionization – ion mobility spectrometry (ESI-IMS) for security applications
  • Demonstration of how a high resolution ion mobility spectrometer can resolve explosives components into individual
    peaks (in practical trace detection applications, the analysis of explosives can be problematic if there are other
    components in the sample that have similar mobilities. These additional components can be other explosives or impurities).
