Electrical Mobility in gas phase


Electrical mobility is the ability of charged particles (such as electrons or protons) to move through a medium in response to an electric field that is pulling them. The separation of ions according to their mobility in gas phase is called Ion mobility spectrometry, in liquid phase it is called electrophoresis. Mobility is defined for any species in the gas phase, encountered mostly in plasma physics.
