Open-Source, Modular Approaches to Ion Mobility Spectrometry

Pulse_Comp_v3Outside of an ionization source and a Faraday plate, a drift tube IMS system is fundamentally comprised of 5 primary components:

  • Reaction/Drift Cell
  • Ion Gate
  • Gate Pulsing Electronics
  • Current to Voltage Converter
  • Data Acquisition System (DAQ)

Within the IMS research community hardware and DAQ solutions are often custom and rarely replicated exactly. In an effort to address this knowledge and resource gap, the links posted below outline a range of solutions to the construction and operation of research-grade ion mobility spectrometers.  It is our sincere hope that this information will be useful to other research groups and encourage others to make suggestions and improvements.  The github links, including those from GAA Custom Engineering are found below:
