WebHow Does FAIMS Work? Field Asymmetric Ion Mobility Spectrometry (FAIMS) is a variant of ion mobility spectrometry – a method of distinguishing charged gaseous molecules according to differences in … WebTrapped Ion Mobility Spectrometry (TIMS) is an IMS technique where ions are propelled through the TIMS tunnel by a gas flow. An electrical field controls each ion from moving beyond a position defined by the ion’s mobility, where the push it experiences from the gas flow matches the force of the electrical field.
