WebIon mobility mass spectrometry (IM-MS) has emerged as a self-standing analytical method in the last decade [664 ]. In IM-MS, ions are generated by pyrolysis, electrospray, laser desorption or others prior to entering a gas-filled mobility drift cell region. In this cell, ions drift at a velocity obtained from an electric field based upon their ... WebIon cyclotron resonance (ICR) mass spectrometers have become increasingly popular with the use of Fourier transform (FT) techniques, the development of superconducting magnets, and the importance of pulsed desorption ionization methods and are now in the forefront of mass spectrometer development.
